Emollients are non-cosmetic moisturisers which come in the form of creams, ointments, lotions and gels. Emollients help skin to feel more comfortable and less itchy. They keep the skin moist and flexible, helping to prevent cracks.
Dry skin, is a very common and harmless skin condition marked by an inappropriate amount of moisture and oil content in the epidermis; the top most layer of the skin.

COSMETICS CLASSIFICATION By Tannu SainiTannuSaini4
Classification of Cosmetics -
Can be classified based on widely used body parts as:
Skin cosmetics
Hair cosmetics
Face cosmetics
Eye make ups
Lip decorators & carers
Nail cosmetics
Sebaceous Gland: small oil-producing gland present in the skin of mammals
Sebaceous glands are usually attached to hair follicles and release a fatty substance, sebum, into the follicular duct and hence to the surface of the skin.
There are more sebaceous glands in the proximity of hair
It is found all over the body except the palms of the hand and soles of the feet.
It is more in the face and head, and few in the forelimbs.
Sweat Gland: a small gland that secretes sweat, situated in the dermis of the skin.
Such glands are found over most of the body and have a simple coiled tubular structure.
It is of two types
Eccrine gland- Most of the body
Apocrine gland- under arms.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

• Skin is the external barrier of the body,
both physical and immunological
• skin is the largest organ of the body, it
constitutes about 16% of body weight
• its total surface area is about 1.2-2.2 m2
• function:
protection, sensory reception, excretion
and thermoregulation

7. SKIN PHYSIOLOGY
7
The skin is the outer most layer of the body. It is
constituted of 2 layers :
• Epidermis:
Stratum corneum : It consist of epidermal cells
lipophilic nature The membrane provides about 10
-15 layers of flattened keratinized dead cells It is 10
um when it is dry.
But It can take up moisture up to 15 -20 % When
occlusive dressing / cream applied over the skin
prevent the evaporation of water It plays a role in
controlling the percutaneous absorption of chemical
substance
9/2/2021
8. • Stratum lucidum: It is thin translucent layer .
• Stratum granulosum : It is consist of keratin
protein.
• Stratum spinosum : It consist of flattened
polygonal cells.
• Stratum germinativum : It consist of
melanocytes
• Dermis:
Dermis /corium It consist of dense network of
structural protein fibres .It is about 0.2-0.3mm
thickness It contains blood vessels,lymphatic
vessels, nerve ending

9/2/2021
9. • Sebaceous gland
Oil is produced in the sebaceous gland , this production is
stimulated by hormones. Oil flows into the hair follicle then onto the
skin surface
Skin Functions
• Epidermis barrier
– Waterproofs
– Protect from UV
• Dermis
– Sweat glands
– Blood vessels
– Nerve endings

10. Some common disorders of skin
10
•
• Hyper pigmentation: This disorder due to abnormal
pigmentation or increased local synthesis of melanin in
the epidermis . This can be further stimulated by
exposure to UV radiation.
Hypopigmentation: This disorder due to less
pigmentation of melanin . which is called as vitiligo.
Acne( pimples)& prickly heat (miliaria) Malfunction of
sebaceous gland and sweat gland Skin scaling is caused
by dandruff and psoriasis
9/2/2021
11. • Psoriasis: It is formation of scaly red
patches particularly on the extensor surface
of the body.
• Dandruff : Flaking of s.corneum and mostly
occurs on scalp due to microbial infection .
• Effects of aging of the skin: Aging affects
the character and function of the skin .
cosmetics are used to partially repair , mask
or overcome such changes Decrease in
elasticity of the skin cause wrinkles due to
less blood supply.

Due to repeated exposure of skin to water,
soap and detergents many times a
day leads to removal of lipids and
other secretions from the skin. Cold
and dry winds are responsible for
chapping of the skin. Chapping
occurs due to loss of moisture from
The skin, which is also associated with
cracking. Water is sufficient to treat the dryness of the
skin but evaporation of water takes place which
makes the skin dry again and no emollient effect is
produced. 24

• These preparation usually contain
synthetic staining materials.
• These preparation are done by two
ways:
9/2/2021
60. • Systemic suntan: These substance produce
suntan by increasing the rate of pigmentation in the
skin.
Eg: psoralen, alkoxy psoralen,8-methoxy psoralen
ect.8-methoxy psoralen is also available in tablet
form i.e 10-20mg is taken orally which increases the
rate of pigmentation within 2-4hrs after the skin has
been exposed to sunlight.
• Stain produced by chemical: Even chemical
substance are capable of staining the skin and
producing artificial suntan. These chemical produce
a stain which is semi-permanent
Eg; Dihydroxyacetone, juglone, lawsone, erythrulose,
ect 69
