Introduction:
Dry skin is a very common skin condition that occurs at all ages. It is characterized by red itchy skin that tends to crack and peel due to loss of moisture. It commonly affects the arms, legs, and feet. A person may develop dry skin naturally, due to a variety of reasons, and its severity varies from person to person.
The skin:
Skin has three layers:
- The outermost layer of skin (the epidermis).
- The middle layer of skin (the dermis).
- The fat layer of skin (the hypodermis) which contains adipose tissue, nerves and hair follicles.
Other names:
Xerosis
Cause:
The skin's sebaceous glands produce a natural oil called “sebum". This oily substance forms a protective barrier on the surface of the skin to prevent it from losing its moisture. So if the skin does not produce sufficient amounts of this oily substance, it loses moisture and becomes dehydrated. There is no single cause for dry skin, but it is often attributed to environmental factors.
Risk factors:
- Ageing.
- Winter and autumn.
- Menopause.
