Mature Skin
Chronological age does not need to determine the condition of mature skin. Environmental factors play a central role. External influences leading to premature skin aging include:
Internal factors determine the normal biological process of aging, which includes:
Skin's structure depends upon lipids from the sebaceous and sweat glands, without which the skin becomes dry and chapped. It then reacts more sensitively to cleansers, whose use also removes more lipids from the skin. As a result, skin becomes rough, cracked, taut and may itch. Estrogen has a beneficial effect on the skin"s moisture balance, but is reduced in menopause. This leads to structural changes in the skin. As we age, the subcutaneous fatty tissue thins, the connective tissue loses its fibrous structure and water-binding capacity. Elastic fibres degenerate, causing wrinkles. Borders between the individual layers of the epidermis become blurred, cells shrink and skin becomes thinner. |
