1. Topical therapy involves applying medicaments directly to the skin or mucosa. Drug penetration is inversely related to the thickness of the stratum corneum and maximal over mucous membranes.
2. Percutaneous absorption of drugs occurs via transcellular, intercellular, or transappendageal pathways across or between skin cells or through hair follicles and glands.
3. Proper topical treatment requires selecting an appropriate agent, considering the affected area and disease state, and defining dosage and duration to maximize efficacy and minimize side effects.
Micro-dermabrasion is a mechanical skin treatment that uses an applicator probe to break down skin cells and debris on the skin's surface. There are two main types of micro-dermabrasion systems - one uses aluminum oxide micro-crystals applied to the skin, while the other uses a diamond tipped applicator. Benefits of micro-dermabrasion include softer, more toned skin with reduced fine lines, wrinkles, acne scars, and pigmentation issues. Precautions must be taken to avoid over-exfoliating the skin, including checking the applicator strength and monitoring the skin's reaction.

Intramuscular injections are administered at a 90 degree angle into muscle sites like the deltoid, gluteus maximus, or vastus lateralis. Subcutaneous injections are given at a 45-90 degree angle into the subcutaneous tissue. Intradermal injections involve injecting a small volume into the dermis to produce a wheal for diagnostic purposes.
Abstract—Scarring is a well recognized sequel of acne. Because of the prevalence of acne scarring and strong negative emotions it engendering affected patients, several approaches have been developed for its treatment with varying success rates. Glycolic acid 50% peels and Salicylic acid 30% Peels are classified as superficial peel and are consider safe in Indian patients. While chemical peels are widely being used in India for various indications. There is a paucity of published studies on the efficacy of chemical peel specifically for acne scars in Indian patients.
Purpose of this study was to evaluate and compare the effectively of these two agents in the treatment of acne scars. Eighty cooperative patients[≥18 years age]with predominantly moderately atrophic acne scarring were randomly divided into 2groups of 40each.Patients of group A received Glycolic acid peels and patients in group B, Salicylic acid was used at 3weeks interval for four sessions. Objective evaluations of treatment response. Subjective assessments of treatment response were also done separately by the researcher, an independent observer and the patients separately.
Both of agents led to significant reduction in the total acne scar score[p< 0.05]but no significant difference was noted between the two peels. Side effects were lesser with Salicylic acid peel.
Hence conclusion was drawn that both 50% Glycolic acid and 30% Salicylic acid peels are safe in Indian skin and equally effective in the treatment of mild to moderate acne scarring.

It discusses the historical perspective, objectives, indications, contraindications, advantages, and disadvantages of local drug delivery. Various drug delivery agents are also described, including Periochip, Atridox, Actisite, Arestin, and Elyzol. The document concludes that local drug delivery is a valuable adjunct to mechanical periodontal therapy but should not be used alone.
Reversal of a HLA dermal filler induced facial artery occlusionDr. Patrick J. Treacy
Severe vascular adverse events, such as occlusion, can occur after treatment with dermal fillers in the glabellar and nasolabial regions. The author proposes that late onset vascular occlusion may be caused by hyaluronic acid expanding and compressing underlying arteries after injection. To treat impending necrosis from filler-induced vascular occlusion, the author recommends higher than normal doses of hyaluronidase, intravenous steroids, and other measures to increase blood flow and oxygen delivery. While most adverse reactions are mild and transient, practitioners must understand vascular anatomy and have protocols in place to promptly treat more serious complications like vascular occlusion.
This document discusses the evaluation of semisolid dosage forms such as ointments, creams, and suppositories. It describes ideal properties of semisolids and categories of semisolid dosage forms. Evaluation methods are outlined for ointments, creams, and suppositories, including tests for content uniformity, penetration, drug release rate, irritation potential, and dissolution. The goal of evaluating these semisolid dosage forms is to ensure quality, safety, and therapeutic efficacy.
The efficacy of Isotretinoin-loaded solid lipid nanoparticles in comparison t...Nanomedicine Journal (NMJ)
- Isotretinoin-loaded solid lipid nanoparticles (IT-SLN) were prepared and found to have a mean particle size of 60 nm and zeta potential of -40 mV. The encapsulation efficiency of isotretinoin in the IT-SLN was 84%.
- An 8-week clinical trial was conducted comparing the efficacy of the IT-SLN to the commercial product Isotrex on 40 human subjects with mild to moderate acne. IT-SLN showed significantly better treatment of non-inflammatory and inflammatory lesions compared to Isotrex.
- IT-SLN also received better global assessment scores from physicians and resulted in fewer side effects than Isotrex, demonstrating its potential as a
Dermal fillers can be used for cosmetic purposes to fill in wrinkles and folds in the skin. Early fillers included collagen from bovine sources and silicone, but these have been replaced by hyaluronic acid fillers which are naturally found in the body. Popular hyaluronic acid fillers currently include Juvederm, Restylane, and Belotero. Placement is typically in the mid-dermis and complications can include infection, bruising, lumps or nodules. Proper technique and avoidance of overcorrection are important to achieve natural results.
The document discusses procedures for eye irrigation, eye drops, and ear irrigation including their purposes, indications, contraindications, complications, principles, guidelines, and the nurse's responsibilities before, during, and after each procedure with the goal of providing concise information on performing and assisting with these common clinical skills.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Restylane®️/Perlane®️ Injection Training Course Certification
1. History of Dermal Fillers
In 1893, the first fat auto-grafting was performed by Dr. Neuber, who successfully
auto-grafted fat into the infraorbital margin in a man with tuberculous ostitis. In
1980’s Dr. Fournier injected fat from liposuction surgery. Average fat survival rate
was around 25%. Bovine collagen was developed in the 1970’s and Zyderm implant
was FDA approved in 1983. However, skin testing was necessary, because 2 – 3%
of the patients had hypersensitivity reactions.
Hyaluronic Acid (HA) is the main polysaccharide in the extracellular matrix. It acts as
a scaffold for collagen and elastin to bind. It also hydrates the skin, because it binds
water. Skin loses elasticity and fullness due to loss of HA. Researchers were able to
grow chains of the polysaccharide and cross link them. Crosslinking varied its
degree of hardness, lift, duration of survival and resistance to heat and degrading
enzymes. HA is now grown by a gram positive bacteria, and called NASHA
(non-animal sourced hyaluronic acid) gel.
Hyaluronic acid was introduced to the US in 2003 with Restylane. Restylane® has
an HA concentration of 20 mg/mL with a gel bead size of 250 μmol and 100 000
units per mL and an estimated 0.5–1.0% cross-linking. Perlane® contains 20 mg/mL
of HA with a larger gel bead size of 1000 μmol and 10 000 units per mL, and less
than 1% cross-linking.
Other fillers followed that contains polylactic acid, calcium hydroxylapatite, and etc.
In addition to volume replacement, these fillers stimulate host response and
endogenous collagen production.
2. Hyaluronic Acid
Hyaluronic Acid has the following favorable qualities:
● Effective, long lasting and degradable
● Allergy testing is not required
● Similar to normal tissue texture
● No special storage requirement
● No need for mixing or preparation
● Typically it does not migrate nor calcify
● Cost-effective
● Safe
Hyaluronic Acid is a component of the extracellular space. In your body, it maintains
structure by binding water and increasing volume. It also is a source of protection
and lubrication of your tissues. Hyaluronic Acid decreases with age. This is also why
it is an ideal dermal filler agent with good bio-compatibility.
In the injectable form it is a polysaccharide compound. It stabilizes in the tissue by
cross-linking which increases tissue residency. Unmodified Hyaluronic Acid has half
life of 24 – 48 hours. Other medical uses of uncross-linked Hyaluronic Acid include
injections in to joints or formulations on topical products. Hyaluronic Acid binds
water after injection and increases the tissue volume. Cross-linked Hyaluronic Acid
also induced fibroblasts to produce endogenous collagen.
Restylane and Perlane
Restylane-L is a gel of hyaluronic acid generated by Streptococcus species of
bacteria, chemically crosslinked with BDDE (butanediol diglycidyl ether), stabilized
and suspended in phosphate buffered saline at pH=7 and concentration of 20 mg/mL
with 0.3% lidocaine. Restylane is a similar gel compound without the 0.3% lidocaine.
Restylane-L is indicated for mid-to-deep dermal implantation for the correction of
moderate to severe facial wrinkles and folds, such as nasolabial folds. Restylane-L is
indicated for submucosal implantation for lip augmentation in patients over the age of
21.
The concentration of Restylane is 20mg/mL. Restylane is implanted in the mid to
deep dermis.
3. Restylane-L combines Restylane with lidocaine, which can help reduce discomfort
during and after treatment. In clinical studies 72% of patients reported significantly
less pain during treatment with Restylane-L vs. Restylane. Patients continued to
experience less discomfort for up to one hour after treatment.
Perlane-L is a sterile gel of hyaluronic acid with 0.3% lidocaine. The median particle
size is between 750 and 1000 microns. Perlane is a similar gel compound without
the 0.3% lidocaine.
Perlane-L is indicated for implantation into the deep dermis to superficial subcutis for
the correction of moderate to severe facial folds and wrinkles, such as nasolabial
folds.
The concentration of Perlane is 20mg/mL. The difference between Restylane and
Perlane is that Perlane has a larger gel particle size than Restylane. Perlane is
implanted into the deep dermis. Therefore, Perlane is a better choice for more
severe facial wrinkles that benefit from a deeper injection into the skin. By combining
lidocaine with Perlane, Perlane-L helps reduce discomfort during and after treatment.
In clinical studies 95% of patients reported significantly less pain during treatment
with Perlane-L vs. Perlane. Patients continued to experience less discomfort for up
to one hour after treatment.
In clinical trials, Restylane persists in the skin for about 6 months. Perlane persists in
the skin for at least 6 months in a majority of patients. Clinical studies show no
significant safety profile difference between Restylane and Perlane. Both products
are biocompatible with the body’s natural hyaluronic acid and no allergy testing is
required.
4. Clinical Study
The results of the blinded evaluator assessment of NLF wrinkle severity for
Restylane and control (Perlane) are presented in Table 15. In the primary
effectiveness assessment at 12 weeks, 77% of the Restylane and 87% of the control

Directions for Assembly
Use the thumb and forefinger to hold firmly around both the glass syringe barrel and
the Luer-Lok adapter. Grasp the needle shield with the other hand. To facilitate
proper assembly, both push and rotate firmly.
Pre-treatment Guidelines
Prior to treatment, the patient should avoid taking aspirin, nonsteroidal
anti-inflammatory medications, St. John’s Wort, or high doses of Vitamin E
supplements. These agents may increase bruising and bleeding at the injection site.
Treatment Procedure
1. It is necessary to counsel the patient and discuss the appropriate
indication, risks, benefits and expected responses to the treatment.
2. Advise the patient of the necessary precautions before commencing the
procedure.
3. A consent form should be utilized.
4. Assess the patient’s need for appropriate anesthetic treatment for
managing comfort, i.e., topical anesthetic, local or nerve block.
5. The patient’s face should be washed with soap and water and dried with a
clean towel. Cleanse the area to be treated with alcohol or another suitable
antiseptic solution.
6. Sterile gloves are recommended while injecting.
7. Before injecting, press rod carefully until a small droplet is visible at the tip
of the needle.
8. Restylane is administered using a thin gauge needle (29 G x ½”). The
needle is inserted at an approximate angle of 30° parallel to the length of
the wrinkle, fold, or lip. For nasolabial folds, Restylane should be injected
into the mid-to-deep dermis. For lip augmentation, Restylane should be
injected into the submucosal layer, care should be taken to avoid
intramuscular injection. If Restylane is injected too superficially this may
result in visible lumps and/or bluish discoloration.
9. Perlane is administered using a thin gauge needle (27 G TW x ½” or 29 G
TW x ½”). The needle is inserted at an approximate angle of 30° parallel to
the length of the wrinkle or fold. Perlane should be injected into the deep
dermis to superficial layer of the subcutis.
7. 10.Inject Restylane applying even pressure on the plunger rod. It is important
that the injection is stopped just before the needle is pulled out of the skin
to prevent material from leaking out or ending up too superficially in the
skin.
11.Only correct to 100% of the desired volume effect. Do not overcorrect. With
cutaneous deformities the best results are obtained if the defect can be
manually stretched to the point where it is eliminated. The degree and
duration of the correction depend on the character of the defect treated, the
tissue stress at the implant site, the depth of the implant in the tissue and
the injection technique.
12.Typical usage for each treatment session is specific to the site as well as
wrinkle severity. In a prospective study of midface wrinkle correction, the
median total dose was 3.0 mL. Based on U.S. clinical studies, the
maximum recommended dose per treatment is 6.0 mL for the nasolabial
folds and 1.5 mL per lip per treatment.
13.Dissection of the sub-epidermal plane with lateral movement of the needle,
rapid flows ( > 0.3 mL/min), rapid injection or high volumes may result in an
increase in short-term episodes of bruising, swelling, redness, pain, or
tenderness at the injection site.
14.When the injection is completed, the treated site should be gently
massaged so that it conforms to the contour of the surrounding tissues. If
an overcorrection has occurred, massage the area firmly between your
fingers or against an underlying area to obtain optimal results.
15.If so called “blanching” is observed, i.e., the overlying skin turns a whitish
color, the injection should be stopped immediately and the area massaged
until it returns to a normal color.
16.If the wrinkles or lips need further treatment, the same procedure should be
repeated until a satisfactory result is obtained. Additional treatment with
Restylane may be necessary to achieve the desired correction.
17.If the treated area is swollen directly after the injection, an ice pack can be
applied on the site for a short period. Ice should be used with caution if the
area is still numb from anesthetic to avoid thermal injury.
18.Patients may have mild to moderate injection site reactions, which typically
resolve in less than 7 days in the nasolabial folds and less than 14 days in
the lip.
8. HOW SUPPLIED
1. Restylane is supplied in a disposable glass syringe with a Luer-Lok fitting.
Restylane-L is co-packed with sterilized needle(s) as indicated on the
carton (29 G x ½”).
2. Perlane is supplied in a disposable glass syringe with a Luer-Lok fitting.
Perlane-L is co-packed with sterilized needle(s) as indicated on the carton,
either 27 G Thin Wall (TW) x ½” or 29 G TW x ½.”
3. A patient record label is a part of the syringe label. Remove it by pulling the
flap marked with three small arrows. This label is to be attached to patient
records to ensure traceability of the product.
4. The contents of the syringe are sterile.
5. The volume in each syringe and needle gauge is as stated on the syringe
label and on the carton.
Adverse Experiences
In three studies, investigators reported the following local and systemic events that
were judged unrelated to treatment and occurred at an overall incidence of less than
2%, i.e., acne; arthralgia; tooth disorders (e.g., pain, infection, abscess, fracture);
dermatitis (e.g., rosacea, unspecified, contact, impetigo, herpetic); unrelated injection
site reactions (e.g., desquamation, rash, anesthesia); facial palsy with
co-administration of botulinum toxin; headache/migraine; nausea (with or without
vomiting); syncope; gastroenteritis; upper respiratory or influenza-like illness;
bronchitis; sinusitis; pharyngitis; otitis; viral infection; cystitis; diverticulitis; injuries;
lacerations; back pain; rheumatoid arthritis; and various medical conditions such as
chest pain, depression, pneumonia, renal stones, urinary incontinence, and uterine
fibroids.
Serious adverse events have been rarely reported. The only serious adverse events
occurring in a frequency of 5 times or greater were abnormal sensitivity
(hypersensitivity), injury to blood supply (vascular accidents), local tissue damage
(necrosis) and infection/abscess. Hypersensitivity reactions have occurred
immediately following implantation and up to 3 weeks and some required
hospitalization.
Reported symptoms included swelling (including severe swelling of lips and face);
redness; itching on chest and back; puffy, burning, watery, and itchy eyes; shortness
of breath; headache; nausea and vomiting. Treatments used included steroids,
diphenhydramine, unspecified intravenous medication, oxygen and various creams.
Most hypersensitivity events have resolved within 1 to 14 days with or without
treatment. Bruising and skin turning white as a result of injury to blood supply
9. (blanching) have occurred immediately following injection with some cases resulting
in necrosis. As a result of the necrosis some patients experienced scarring and dark
spots on the skin.
Moderate to severe infection/abscess formations have occurred with an onset
ranging from 3 days to one week post injection with approximately one month to
resolution. Symptoms included swelling, redness, pain and hard nodules. Some
patients required hospitalization for incision and drainage and intravenous (IV)
antibiotic therapy. Culture results for the reports of infection or abscess varied.
Treatment included various antibiotics and steroids in some cases.
Adverse events that have occurred at the injection sites include: discoloration,
bruising, swelling, lumps/bumps, redness, pain, scarring, numbness/tingling,
necrosis, and low blood supply due to blockage of a blood vessel (ischemia).
Additional events include: bacterial infections, fainting (vasovagal reactions), herpetic
eruptions, dilated small blood vessels (broken capillaries), and inflammatory
reactions (swelling, redness, tenderness, hardness and acneform papules).
WARNINGS
Defer use of Restylane at specific sites in which an active inflammatory process (skin
eruptions such as cysts, pimples, rashes, or hives) or infection is present until the
process has been controlled.
Injection site reactions (e.g., swelling, redness, tenderness, or pain) to Restylane
have been observed as consisting mainly of short-term minor or moderate
inflammatory symptoms starting early after treatment and with less than 7 days
duration in the nasolabial folds and less than 14 days duration in the lips. Rare
post-market reports of immediate post-injection reactions included extreme swelling
of lips, the whole face and symptoms of hypersensitivity such as anaphylactic shock.
Restylane must not be implanted into blood vessels. Localized superficial necrosis
and scarring may occur after injection in or near dermal vessels, such as in the lips,
nose, or glabellar area. It is thought to result from the injury, obstruction, or
compromise of blood vessels.
Delayed onset inflammatory papules have been reported following the use of dermal
fillers. Inflammatory papules that may occur rarely should be considered and treated
as a soft tissue infection.
Injections of greater than 1.5 mL per lip (upper or lower) per treatment session
significantly increases the occurrence of the total of moderate and severe injection
10. site reactions. If a volume of more than 3 mL is needed to achieve optimal
correction, a follow-up treatment session is recommended.
In a meta-analysis of all Restylane Pre-market Approval Studies (that included 42
patients under the age of 36 and 820 over the age of 35), the incidence of swelling
was higher in younger patients (28%) compared to older patients (18%) and
incidence of contusion was higher in older patients (28%) compared to younger
patients (14%). The majority of these events were mild in severity.
Precautions & Contraindications
PRECAUTIONS
1. Restylane is packaged for single patient use. Do not resterilize. Do not use
if package is opened or damaged.
2. Based on U.S. clinical studies, patients should be limited to 6.0 mL per
patient per treatment in wrinkles and folds such as nasolabial folds and to
1.5 mL per lip per treatment. The safety of injecting greater amounts has
not been established.
3. The safety or effectiveness of Restylane and Restylane-L for the treatment
of anatomic regions other than nasolabial folds or lips has not been
established in controlled clinical studies. Refer to the clinical studies
section for more information on implantation sites that have been studied.
4. The safety or effectiveness of Perlane and Perlane-L for the treatment of
anatomic regions other than nasolabial folds has not been established in
controlled clinical studies.
11. 5. The safety and efficacy of Restylane for lip augmentation has not been
established in patients under the age of 22 years.
6. As with all transcutaneous procedures, Restylane implantation carries a
risk of infection. Standard precautions associated with injectable materials
should be followed.
7. The safety of Restylane for use during pregnancy, in breastfeeding females
or in patients under 18 years has not been established.
8. Formation of keloids may occur after dermal filler injections including
Restylane.
9. Restylane injection may cause hyperpigmentation at the injection site.
10.The safety profile for Restylane lip augmentation in persons of color is that
the incidence of adverse events was similar to the overall study population,
with the exception that swelling occurred more frequently in persons of
color.
11.Restylane should be used with caution in patients on immunosuppressive
therapy.
12.Bruising or bleeding may occur at Restylane injection sites. Restylane
should be used with caution in patients who have undergone therapy with
thrombolytics, anticoagulants, or inhibitors of platelet aggregation in the
preceding 3 weeks.
13.After use, syringes and needles should be handled as potential biohazards.
Disposal should be in accordance with accepted medical practice and
applicable local, state and federal requirements.
14.The safety of Restylane with concomitant dermal therapies such as
epilation, UV irradiation, or laser, mechanical or chemical peeling
procedures has not been evaluated in controlled clinical trials.
15.Patients should minimize exposure of the treated area to excessive sun,
UV lamp exposure and extreme cold weather at least until any initial
swelling and redness has resolved.
16.If laser treatment, chemical peeling or any other procedure based on active
dermal response is considered after treatment with Restylane, there is a
possible risk of eliciting an inflammatory reaction at the implant site. This
also applies if Restylane-L is administered before the skin has healed
completely after such a procedure.
17.Injection of Restylane into patients with a history of previous herpetic
eruption may be associated with reactivation of the herpes.
18.Restylane is a clear, colorless gel without particulates. In the event that the
content of a syringe shows signs of separation and/or appears cloudy, do
not use the syringe and notify Medicis Aesthetics Inc. Glass is subject to
breakage under a variety of unavoidable conditions. Care should be taken
with the handling of the glass syringe and with disposing of broken glass to
avoid laceration or other injury.
12. 19.Restylane should not be mixed with other products before implantation of
the device.
CONTRAINDICATIONS
1. Restylane is contraindicated for patients with severe allergies manifested
by a history of anaphylaxis or history or presence of multiple severe
allergies.
2. Restylane contains trace amounts of gram positive bacterial proteins, and
is contraindicated for patients with a history of allergies to such material.
3. Restylane is contraindicated for patients with bleeding disorders.
4. Restylane is contraindicated for implantation in anatomical spaces other
than the dermis or submucosal implantation for lip augmentation.
5. Restylane-L and Perlane-L should not be used in patients with previous
hypersensitivity to local anesthetics of the amide type, such as lidocaine.
Injection Technique
Serial Puncture
This is created with multiple, closely spaced injections along a wrinkle. It is used for
superficial dermal injections and demands precise placement of the filler or gaps will
be found in between the injection site. It is undesirable due to the multiple puncture
wounds it generates. The needle is inserted bevel up. The product is dispensed like
drops along the fold. You should massage to prevent nodule formation.
Linear Treading
This is created by completely inserting the needle in the wrinkle up to the hub of the
needle and injecting the product along the track as a thread as you slide out the
needle. It demands continual pressure and even distribution of the product as you
remove the needle. You must stop your injection several millimeters prior to
completely removing the needle from the skin to avoid superficial placement or
leaking products above the skin. The skill of pushing the plunger of a syringe as you
are pulling back syringe from the skin is a skill that may be difficult for some, but can
be mastered with practice. Linear threading may be suboptimal for some deep folds
as it does not give additional structural support.
Fanning
This is created by puncturing the epidermis once, as in the linear threading
technique, and before the needle is completely removed from the skin, you “fan”
clockwise or counter-clockwise the needle in a fan pattern to create a triangular
13. shape. The additional spacing of the fanning injections depends on the size of the
triangular area you want to fill. You must avoid over injecting of the proximal end of
each “fanning” as product may overlap and create lumps. This is excellent in deep
folds as it props up adjacent skin that may be hanging over the fold.
Injection techniques such as fanning, rapid injection, rapid flow rates, and higher
volume caused an increased incidence of adverse reaction. Multiple punctures or
deep subcutaneous injection did not affect the rate of adverse effects.
Aging Skin
Loss of subcutaneous volume, thinning of the skin, changes in bony structures, skin
laxity due to loss of collagen and elastin, and downward gravitational shift of the skin
and underlying tissues causes aging. Laugh lines and marionette lines become
more prominent. The lips become thin, flat and deflate. Vertical lines form above
and below the lips. Oral commissures turn downward.
Consultation
Good patient selection and education is paramount to a successful practice. Many
patients confuse Dysport® or Botox® Cosmetic with Dermal Fillers. A patient may
want you to inject Dysport® in the lips to make them fuller. Educate your patients
the difference between the two.
First, obtain a full medical history and physical exam to rule out any potential
contraindications.
Then, ask the patients what they are interested in correcting. Then take a look at
these areas: nasolabial folds, marrionette lines, smile lines, lips, and vertical lines
away from the lips. Patient will typically ask what areas they should inject. We also
recommend that you avoid pointing out someone’s defects; but rather demonstrate
on their faces, the areas that a Dermal Filler can be injected.
Are the lines too deep? You may consider performing a stretch test of the wrinkle by
stretching them with your thumb and your index finger to see if the wrinkle can be
flattened. A wrinkle that does not easily flatten or that requires your fingers to spread
far apart to flatten may not be completely corrected or may require additional
treatments. Remember that not all folds can be filled to full correction due to tissue
hanging over the fold or other causes, such as scar tissue.
14. When do they want the treatment? If your patient’s wedding is less than a week
away and she has never tried Restylane on her lips before, then this is probably not
a good time to start.
Discuss the possibility of a touch up in the future and the total cost of the treatment
should a touch up be required.
Ask about your patient’s pain tolerance. Discuss the various pain control options.
Take the time to listen to your patients and educate them. Some may have too
many areas that they want treated. Some may want you to use one syringe to fill all
these areas, even though the results will be suboptimal. Some may have areas that
they want filled that you don’t see a defect in. Set realistic goals. Sometimes, you
may be better off sending them away without a treatment to avoid disappointing
them. Dissatisfied patients rarely comes back.
Pre-Injection Checklist
Photo; Keeping a photographic record of the patient’s pre-injection feature may help
avoid misdirected blame.
Evaluate for asymmetry prior to injection; This is also important to point out and note
to yourself if the patient wants symmetry. You want make sure that you have enough
product left in the syringe to treat each side evenly.
Clean and anesthetize the area; Use alcohol wipes liberally. Offer the patient a
topical anesthetic, or ice to cool the area prior to the injection.
Use the needle provided by the vendor;
Fully seat the needle to the hub; This will decrease the possibility of needle
disengagement from the syringe. A needle that is not fully attached to the syringe
can result in the needle disengaging from the syringe and spilling your product on
your patient’s face.
Point the eye of the needle face upwards towards the surface of the skin.
Push the plunger until the droplet appears at the tip of the needle; You want to
remove the air that is inside of the needle hub. If the patient has a history of cold
sores, then you should discuss with the patients about pretreatment with antiviral
medication prior to any injection around the mouth.
15. Injection Technique
Injection
1. Insert the needle into the middle to deep dermis.
2. You may stretch the skin to aid insertion.
3. The contour of the needle should be BARELY or NOT visible depending on
the type of filler and the type of wrinkle being injected.
4. If you are injecting using the threading technique, then remember to apply
even pressure on plunger of the syringe while slowly pulling the needle
backwards.
5. Remember to stop the injection before the needle is pulled to the skin to
prevent losing material out of the skin or to prevent an injection that is too
superficial.
6. Superficial injection may cause a bluish hue to the skin, call Tyndall effect.
This can either be massaged deeper, squeezed out, or dissolved with
Hyaluronidase.
7. When fanning, do not completely remove the needle from the skin, angle
the syringe (fanning) and reinsert the needle to the end of the hub.
8. Direction of the angling depends on the shape of the fold.
9. If blanching occurs, then stop the injection. You may be injecting into or
near a blood vessel. Massage the area until the skin returns to a normal
color.
10.One should always feel the resistance of the dermis as one is injecting. If
the injection has too much or too little resistance, then you are likely in the
wrong plane.
16. 11.Wrinkle should be visibly lifted and filled by the end of the treatment.
Post Injection
No empty spaces or lumps should be felt along the injection. Correct to 100% – do
no over or under-correct. Gently massage the injection site to contour the product
with the surrounding tissue after your injection. When you feel lumps or bumps, a
gentle massage between your fingers or over an underlying bone will typically flatten
the protrusion.
Reassure the patient that the lump will likely go away. Arrange for a follow up in a
week. If the lump is still apparent at the follow up appointment, then use
Hyaluronidase. It can be difficult to judge the symmetry of your product placement
immediately after the injection due to localized swelling and bruising.
This is true, especially in the lips. If you notice asymmetry and you feel that you have
placed the products evenly, then it is best to invite the patient back in 1 week for
re-evaluation. Any mild to moderate swelling due to localized swelling, internal
bruising, and/or product placement should resolve in a few days. Offer your patient
an ice pack to minimize swelling and bleeding.
Nasolabial Folds
Correction of the nasolabial fold is the most common site for correction with
NASHA™ fillers. Malar fat pad moves medially and inferiorly due to loss of collagen
and skin elasticity and cause the nasolabial folds or laugh lines. The Nasolabial fold
is the visible line or groove from the lateral edges of the nose to corners of the
mouth. Heavy cheeks due to aging or obesity may increase the depth of the lines.
Depending on the age, the fold may be superficial or deep. Therefore, older patients
may benefit from Perlane®.
For shallow to medium folds, use linear threading with fanning to correct the folds.
Start from the inferior position and insert the needle superiorly. Inject 0.05mL to
0.1mL per injection.
Fanning is recommended up by the nose and possibly throughout depending on the
level of correction visualized. Concentrate your fanning on the upper Y-shaped area
below the naris and lateral to the ala. There is less movement of the facial muscles
in this area and correction persists well. In this position, the nasal artery runs near,
so we recommend that you pull back on the syringe plunger to make sure that no
17. flash of blood is seen if you feel that the injection may be too deep. Also, injecting
slowly low amount of volume will also prevent intra-arterial injection.
Further down the fold towards the oral commissure, the duration of correction is
shorter due to increase muscle movement. Correction may be more challenging due
to the lack of underlying bone and the sagging tissue from the area of the
cheekbones.
After you are finished with your injection, place a glove thumb on top of the fold and
one or two fingers on the inside of the mouth. Gently mold along the injection site to
feel for nodules or bumps. HA fillers are malleable and can be molded.
You may see multiple fine lines lateral to the nasolabial fold. Resist the urge to inject
them as they are typically due to dynamic movement. While at rest, the lines may
appear diminished, with movement, implanted fillers may be visible as cords on the
patient’s face.
Oral Commissures
Lateral commissures of the mouth may begin to turn downward as one age. Patients
may complain that the corners of their mouth look sad. The goal of this treatment is
to fill the folds and lift the corners of the mouth. Deep depressions here may require
serial puncture technique, while linear threading is preferred for shallow, longer
grooves. The injection may extend down into the melomental fold in older patients.
You may ask your patients to open their mouth slightly to aid your injection.
Augmentation in the mouth corners typically does not last as long as in other areas.
Inject 0.05mL to 0.1mL per injection.
Melomental Fold
Melomental fold (MMF) is the fold running inferiorly from the oral commissure
towards the mandible. Loss of collagen and elasticity, gravity and boney atrophy
causes the formation MMF. Prominent MMF gives the appearance of anger or
sourness.
MMF may look like a single line when looking at the face straight on. A more three
dimensional observation, by looking up towards the nose superiorly, may
demonstrate a deeper groove or delta. Techniques such as linear threading or serial
puncture may be inadequate for more advance folds. A scaffolding-like structure
may have to be formed using fanning or cross-hatching technique.
Inject into the deep dermis vertically from inferior to superior direction. Horizontal
injections should be placed from medial to lateral direction to avoid injecting the
18. facial vein which can be found lateral to the MMF. Layering may be required for
deep MMF. MMFs benefit from thicker fillers, such as Perlane. Inject along the fold
0.05mL to 0.1mL per injection. Avoid inadvertent injections into the lip as this may
cause unwanted lip enhancement or lumping in the lower lips. Remember that while
most patients can tolerate injection into the nasolabial folds, MMF injection tend to
be more painful.
Lips
Lip volume reach full thickness by the mid-30s. They are a defining feature of
beauty and youth. As we age, vermilion border thin, corners of the mouth droop,
philtral ridge and cupid’s bow flatten, and fine lines appears on the lips. Upper lip
typically becomes thin and elongated, while the lower lip becomes thin and roll
inwards. Activity of the orbicularis oris cause radiating perioral lines. Patients often
complain about bleeding lipstick lines.
Lips are the most challenging of all the areas to fill properly. Issues to address
include to following: proportional lip relative to the face, proportional upper and lower
lip fullness, sharp, well defined vermilion borders, distinct Cupid’s Bow peak and
philtral columns, and upturned oral commissure. Typically, the lower lip is fuller than
the upper lip. The ideal ratio of upper lip to lower lip is 1 : 1.6, based on the
Fibonacci proportion.
There are two distinct goals typically depending on the patient’s age.
Younger individuals typically want to enhance the size and shape of the lips. A
young patient with naturally fuller lip forms may be more technically challenging.
Some may bring in photos requesting specific outcomes. It is important to ask if the
patient desires fuller lips or a completely different shape. Lip volume enhancement
increases the height of the vermilion border and increases lip circumferentially. This
may cause a “duck lip” appearance. Small volume injections are always
recommended for first time treatments. Even a small volume of filler (0.1 – 0.3mL)
can make a difference in appearance of the lips.
Older individuals typically want to correct or restore their lips back to where they
were rather than to increase their size. Detailed consultation is required for older
patients as they may not want eversion of the lips or not want their lips to look “fake”.
Patients with lipstick bleeding may require additional treatments such as laser
resurfacing or chemical peel. Determine the patient’s goal for the correction.
Most patients feel moderate amount of pain during the injection. HA products with
lidocaine help reduce discomfort. Nerve blocks and topical anesthesia cream are
19. other ways to minimize pain. If you perform any nerve blocks, then it is important to
work quickly after these as the numbing can distort the position of the patient’s lips.
We recommend using the threading technique to minimize the number of punctures.
Injecting along the vermilion border and wet – dry junction will enhance the volume
of the lips.
To increase the size of the lips, insert the needle 1-2mm away from the vermillion
border towards the mucosa border to evert the lips. Injecting near the vermilion
border increases size, shape, lift and contour. This will give the lips a “ski jump” like
appearance where the vermillion border will curve outwards. Injections at the
vermilion borders should be done with caution, as too much filler here can give your
patients a “duck-like” appearance to the lips. Start with 0.05ml per injection and
increase the amount depending on the level of correction desired. Injection can start
from the lateral edge or the medial peak of the Cupid’s Bow of the upper lip.
Typically, injections near the vermilion border should be done prior to injections near
the wet-dry border. To increase the volume of the lips, insert the needle 3-5mm
away from the vermillion border near the wet-dry border to plump up the lips. This
will not evert the lip edges. Start with 0.05ml per injection and increase the amount
depending on the level of correction desired.
To increase the philtral column, insert the needle at the junction of the Cupid’s bow
and philtral column, and advance superiorly. Try to inject a slightly greater amount
of filler inferiorly to create a natural contour of the column. Inject 0.025 to 0.05ml per
column.
Vertical lip lines, or smoker’s or lipstick lines vary from fine lines to deeper grooves
and injection technique will vary. Injection can be directly into the lines,
perpendicular to the lines, or along the vermilion border. Treat this area
conservatively and use very small amounts so that the area above the vermilion
border does not become swollen.
Lips are the focal point of the lower face. Therefore, mistakes are more apparent.
Due to its high vascular tissue, mistakes are more likely to produce adverse events
than other areas. Immediate, short-term swelling is common. Bruising is frequent.
This may cause the injector to overcorrect one area in response to edema or
hematoma. If the patients lips are symmetric prior to inject, then insure that equal
amount of filler is implanted to maintain symmetry.
Asymmetric lips obviously require different amounts to create symmetry. Application
of an ice pack after the injection can diminish these immediate complications.
20. Extravasation into small bumps may be visible during the injection. Massage these
lumps and guide the product into the desired location. We recommend a
conservative treatment with small volume injections for first time treatments.
Complication Management
HA fillers have an impressive safety record. Despite this impressive safety record,
adverse events occur when injecting HA fillers. It is important to be familiar with
potential complications and management.
Complication can be divided into early and delayed in time of occurrence, and minor
and major in severity.
Early minor complications include bruising, pain, edema and erythema. These can
occur immediately or within hours and resolve within a week. Most patients will
develop at least one of these local injection site reactions, so it is important to
discuss this with them. Pretreatment with anesthetic or ice prior to treatment is
recommended to minimize pain in site that contains high sensory innervation, such
as the lips. Avoiding anticoagulants and supplements that are not medically
necessary will minimize post injection ecchymosis. Some use homeopathic ointment
called Arnica in reducing ecchymosis. Helenalin, an extract of Arnica, has shown to
have anti-inflammatory effects, although clinical studies are not conclusive.
Other early minor complications of asymmetry, lumpiness, or bluish discoloration are
typically due to injection technique. Incorrect filler placement can cause nodules or
papules. When the filler is implanted too superficially, a bluish hue is visible (Tyndall
21. effect). Such reactions can be treated with manual massage, aspiration, incision and
drainage, or hyaluronidase.
A rare early major complication is an anaphylaxis due to an immediate
hypersensitivity reaction. It is estimated that 1 in 10,000 individuals with HA report a
mild to severe hypersensitivity reaction. In 2005, a patient developed
angioedema-type of reaction 1 hour after Restylane injection into the lips. This
patient responded to corticosteroid injection with complete resolution. It is always
recommended that you should have a protocol in your office should any such
emergency should arise.
Cellulitis is a complication seen with any injection procedure. Common bacterial
causes are Staphylococcus and Streptococcus. Lesions should be cultured and
treated with antibiotics. The use of chlorhexidine will minimize the risk of infection.
Trauma from the injection can trigger a recurrent herpetic lesion. Prophylactic
antiviral treatment is recommended when injecting the lips. Also, injection should be
avoided during an active herpes outbreak.
Inflammatory nodules can occur if bacteria is injected with the filler, and the HA
encapsulates the bacteria within the skin. These inflammatory nodules will be red
and painful. Incision and drainage should be performed, with cultures, and antibiotic,
such as clarithromycin should be started for at least 2 – 6 weeks. The use of steroid
can worsen the situation. Patients with diabetes, immunocompromised, chronic
sinusitis, or chronic dental problems should be treated with care.
Delayed major complication is the formation of granulomas which can occur 6
months after the injection. HA fillers are rarely linked to granuloma formation, but it
has been reported in 0.1% of the patients who are typically injected with permanent
or semi-permanent fillers. The body mounts a foreign body reaction with fibrosis
occurring at the injection site. This can be treated with steroid injections, surgical
excision, or hyaluronidase.
Delayed hypersensitivity reaction can also occur. In 2009, a case report was
described a patient who developed acute facial angioedema with urticarial 3 weeks
after Restylane in her nasolabial folds.
The most severe, delayed complication is tissue necrosis, due to direct blockage of a
vessel, compression near the vessel, or injury to the vessel. This has been reported
in 0.09% of the patients who received collagen injections. The patient will
experience delayed capillary refill and pain, followed by a mottled pattern of purple
discoloration, and ulceration due to necrosis. This can occur in the glabellar area
22. due to blockage of the supratrochlear or supraorbital artery and the alar or nasal
area due to the blockage of nasal arteries. This can also occur along facial and
angular artery. A thorough understanding of the facial anatomy is recommended to
prevent this complication. Steps such as aspiration, slow anterograde injection,
constant needle motion, using small particle size fillers, superficial use, avoiding
injection near vessels, and blunt tip cannulas can help reduce the risk of
intravascular injection. This can be treated with massage, heat application,
nitroglycerin paste (1/2 inch of 2% nitroglycerin) to vasodilate the area, and
hyaluronidase to remove the filler. When nitroglycerin is used topically, the patient
should be warned of the potential side effects, such as headache, bradycardia, and
hypotension.
Hyaluronidase
Hyaluronidase is an enzyme that breaks down and hydrolyzes hyaluronic acid.
Multiple reports have been documented on successful elimination of unwanted HA
implantation. Hyaluronidase has been used to correct asymmetry, overcorrection,
Tyndall effect and vascular occlusion. Hyaluronidase will dissolve the filler and
reduce edema, which will help minimize occluded vessel pressure.
Hyaluronidase is diluted with saline in 1:1 ratio. Skin testing is mandatory when
using hyaluronidase. Inject 3 – 5 units intradermally. A wheal formation within 5
minutes and persisting for 20 -30 minutes with localized itching is a positive skin test.
Total of 10 – 30 units should be injected per 2 X 2 cm area of impending necrosis.
Please check the package insert for any Hyaluronidase product for complete
instructions and warnings and contraindications.
Conclusion
During the consultation phase, collection of a thorough medical history, including
medications and allergies, is essential. The injector must be aware of the techniques
and understand the depth of the implantation.
A minor complication in your eyes may not be minor in your patient’s eyes. As one
can clearly see, using Hyaluronic Acid based fillers offers additional options in
treating any complications. Early recognition, education, treatment and
psychological support will minimize any potential disasters.
A detailed consultation is a must. Educate your patients. Under-promise and
over-deliver.
