What do Lactic Acid Peels Do? Exfoliating the surface of your skin Deep cleaning pores Fading dark marks Improving hyperpigmentation Evening out skin tone Brightening and lightening skin Improving the appearance of light wrinkles Stimulating natural collagen production

2.  An alpha hydroxy acid.
 Occurs naturally – Sour milk, yogurt, tomato
juice.
 Largest molecules among AHAs – slower
penetration.
 Less irritation. More hydrating
 Lunch time procedure – no peeling
 Good - dry & sensitive skin

3.  Facilitate dissociation of epidermal cells.
 desquamation of stratum corneum ,
regeneration.
 hyaluronic acid in skin – water holding capacity –
moisturizing effect.
 Epidermis - thinned, smoother, improved texture.
 Reverse – photodamage, wrinkles, brown spots &
roughness of skin

4.  pH or pKa - determinant factor for all acids.
 L.A > pH 3.5 – Cosmetics as a moisturizer.
 pH < 3.5 in higher concentration – peeling agent
 15 – 30 % solution.
 30% (pH 2.3) – used for sensitive, dry, oily, acne
prone, dehydrated skin.
 40% ( pH 2.2) – used for dry, dehydrated, normal
skin, perfect for first time peel
users

5.  50% (pH 2.0) – wrinkles , all skin types.
 Pure lactic acid – 92% (pH 3.5) – peeling agent
forprofessional use .

6.  Melasma
 Acne
 Hyperpigmentation
 Sunburns
 Dark circles
 Photoaging/Photodamage
 Actinic keratosis
 Seborrheic keratosis

7.  Active viral/bacterial infections
 Inflammatory dermatoses
 Unrealistic expectations
 Photosensitising drugs
 Resurfacing procedures - last 6 months

8.  Exfoliating the surface of your skin
 Deep cleansing pores
 Fading dark circles
 reducing hyperpigmentation
 Evening out skin tone
 Brightening & lightening skin
 Reducing the appearance of wrinkles
 Stimulating natural collagen production

9.  L.A – Texture: sticky, yellowish solution
 G.A - Watery, clear liquid.
 L.A – expensive, fade hyperpigmentation better,
less harsh.
 If you never got a peel done before – start with
L.A then try G.A

11.  It is a component of jessener’s peel, Melaspeel
KH (see notes down).
 Claze (Arginine HCl, Lactic Acid, Kojic Acid,
Urea, Arbutin, Citric Acid): Facial rejuvenation &
peri-orbital hyperpigmentation, lip lightening,
fine wrinkles.
 Actipeel (Lactic acid 82%): Skin rejuvenation,
ageing, melasma and skin lightening.
 Pyrulac (Pyruvic Acid 25%, Lactic Acid 25%):
photo damaged skin, body pigmentation &
superficial wrinkles.

12.  Pre peel assesment
 Explain the procedure to the patient
 Priming
 Consent form/photographic documentation
 Application procedure – similar to other AHA
peels.

14.  Peel application should be in the order:
 Forehead > cheeks > chin > perioral >
periorbital.
 We do this in this order because peel should
be applied from area of thick skin to thin
skin .
 It is thickest In the area of forehead
 Forehead should be neutralized last.

16. Jessner’s peel
Lactic acid 29%

18.  Large molecular wt – slower penetration – less
irritation
 Used on sensitive skin & Rosacea.
 L.A – is a humectant – used on dry skin.
 Useful in improving the barrier function of the
skin
 Naturally occuring in the skin – allergic reactions
rare.
 Less downtime – normal skin 3 – 4 days

19.  Improvement is gradual.
 Burning & irritation at times.
 Less used singly as a peeling agent.
