AGING of the skin and peculiarities in BLACK AFRICANS

Abstract

Wrinkling of the skin is a major feature of the aging skin. Its onset is delayed in blacks compared with the Caucasians. It is however becoming a reason for consultation at the cosmetic and beauty centres in Nigeria. With more individuals growing older in the developing world ageing concerns and consultations will increase. This review highlights both intrinsic and extrinsic causes which contribute to skin aging.

Intrinsic factors are due to reduction in number and function of cells seen with aging. The black skin develops pigmentary abnormalities as it ages. Reduction in melanocyte function leads to graying of hair and hypopigmented spots on the skin, idiopathic guttate hypomelanosis. Increase in melanocyte function in some areas present as palmo plantar pigmentation.
Facial pigmentation is also seen with aging. Modifiable extrinsic factors which contribute to ageing are discussed. Alopecia is common in the elderly African
female possible from genetic predisposition but mostly from previous traumatic hair care practices.

There is a need to educate blacks on the dangers of excessive sun exposure and a need for sun avoidance or use of sun screens when necessary. Dermatologists should also improve their knowledge of skin aging so as to offer the proper advice of management to the population.
