The Development of Skin and Aging
Skin ageing refers to a group of common conditions and changes that occur as people become older. Changes in the skin are one of the most visible signs of ageing. The ageing process has a number of effects on the skin. The epidermis thins and turnover slows substantially. Wrinkles and sagging skin are indications of ageing. Hair whitening or greying is another visible sign of ageing. Environmental influences, genetic makeup, diet, and other factors all have an impact on skin changes. The outer skin layer (epidermis) thins with age, despite the fact that the number of cell layers stays constant. Melanocytes (pigment-containing cells) are becoming fewer in number. The surviving melanocytes grow in size.
