Dry Skin
Dry skin can be a big problem even when it is not necessarily a disease, where the skin is red, scaly and itchy. It does seem to be part of the group that includes eczema and the problem is usually worse in autumn and winter.
Dry skin is most common on your face, hands, arms and legs and as you age, dry skin becomes more likely because as people get older, the number of sebaceous glands that give out a type of oil in the skin are reduced, as is the skin's ability to hold moisture.
It appears both the skin's ability to hold water and how well it protects the body, depends on the amount of fat the outer layer of skin contains. This outer layer is known as the epidermis.
Genes also play a role. If relatives suffer from dry skin, you're more likely to develop the condition. In extreme cases, fish-like scaling of the skin is sometimes seen (ichthyosis).
Over-use of soap and water, a dry, warm indoor climate, excessive sunbathing and other environmental effects have a great influence on how dry the skin can become.
