Question

Jane’s mother has always told her to take good care of her skin and to avoid chapping and scratches. Aside from aesthetic reasons, why is this a good idea? Describe the type and function of skin cells.

Answer 1

Ans) UNDERSTANDING THE FOUR SKIN TYPES: NORMAL, DRY, OILY AND COMBINATION

Normal skin
‘Normal’ is a term widely used to refer to well-balanced skin. The scientific term for healthy skin is eudermic.

Dry skin
‘Dry’ is used to describe a skin type that produces less sebum than normal skin. As a result of the lack of sebum, dry skin lacks the lipids that it needs to retain moisture and build a protective shield against external influences

Oily skin

‘Oily’ is used to describe a skin type with heightened sebum production. This over production is known as seborrhea.

Combination skin
Combination skin is, as the name suggests, skin that consists of a mix of skin types.

The skin has many important functions. The skin:

- Provides a barrier. It keeps organisms that could harm the body out. It stops water from entering or leaving the body.
- Controls body temperature. It does this by making sweat (or perspiration), a watery substance that cools the body when it evaporates.
- Gathers information about your environment. Special nerve endings in your skin sense heat, pressure, cold, and pain.
- Helps the body get rid of some types of waste, which are removed in sweat.
- Acts as a sun block. A pigment called melanin blocks sunlight from getting to deeper layers of skin cells, which are easily damaged by sunlight.
