title: Skin care.
abstract: Skin ageing is a continuous process that affects skin function; as people age, their chances of developing skin-related disorders increase. As a person ages the epidermis becomes thinner and the cells are less tightly bound to each other; they are less able to retain water so the skin becomes drier. The number of Langerhans cells and melanocytes decrease, increasing the risk of infection and skin cancer and reducing the ability to heal. In the dermis the number of mast cells which have a protective function, and fibroblasts which have a role in wound healing, steadily decline.
