3. INTRODUCTION
• Cosmetics arise from a Greek word kosmeticos which
means adorn.
• If any material used for beautification or improvement of
appearance is known as cosmetics.
• In the last 3-4 decades the use of cosmetics has
increased in among in females and males The cosmetics
are external preparation are meant to be applied to
external parts of the body .
• In other words they may be applied to skin, hair and nails
for the purpose of covering colouring, softening,
cleansing , nourishing ,and protection.

5. SKIN
• 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

6. SKIN STRUCTURE
6

7. SKIN PHYSIOLOGY
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
7

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
8

9. Skin Functions
• 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
• Epidermis barrier
– Waterproofs
– Protect from UV
• Dermis
– Sweat glands
– Blood vessels
– Nerve endings
9

10. Some common disorders of skin
• 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
10

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.

during day time. These cream provide
emollient as well as protective action to
the skin against environmental
condition by forming a semi-occlusive
residual film. This film is neither greasy
nor oily.
3.VANISHING CREAM
They are oil in water type of emulsion. When applied
on the surface of the skin, they spread as a thin oil less
film which is not visible to naked eye. Hence, they are
called vanishing creams. They are used to hold powder on

24. 5.HAND AND BODY CREAM
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

25. Properties:
1.They should be easy to apply.
2.They helps in softening or imparting
emollient effect to hands.
3.They should not leave behind sticky film
after their application.

morning where as massage cream are the
preparation which are gently applied and
rubbed on the skin through massage
technique. These creams exhibit moisturizing
and emollient action and thus prevent dryness
of skin.
27

28. • Why does skin becomes dry?
when stratum corneum is exposed to low
humidity, excessive loss of water takes place
with attributes to dryness of skin.
When the lower layer of epidermis does not
hydrate properly.
when the skin is in contact with soap or
solution of detergent for long time.
28
