Skin is affected by two types of aging -- intrinsic aging and extrinsic
aging.
Intrinsic aging is inevitable. Genetic and chronological in nature, it is
caused by the normal aging process. Visible signs include:
- dry
skin
- wrinkles
- loss
of skin elasticity
- irregular
skin color
Extrinsic
aging, which is environmental, is much more dramatic. Caused almost exclusively
by sun and environmental exposure, it is the primary factor behind the visible
signs of aging skin such as dryness, sun damage and deep wrinkling. Additionally,
nearly 85% of all aging skin is sun-induced, while 80% of sun-related skin
damage is due to sun exposure before the age of 18.
The most significant changes in sun-damaged skin are:
- increased
roughness
- increased
hyperpigmentation
- greater
loss of elasticity
- greater
wrinkling
- increased
risk of skin cancer
