Skin changes are among the most visible signs of aging. Evidence of increasing age includes wrinkles and sagging skin. Whitening or graying of the hair is another obvious sign of aging.

Our skin is at the mercy of many forces as we tend to age: sun, harsh weather, and unhealthy habits. However we are able to take steps to help our skin keep supple and fresh-looking.

How your skin ages can rely on a range of factors: your life style, diet, heredity, and other personal habits. for example, smoking will produce free radicals, once-healthy oxygen molecules that are currently hyperactive and unstable. Free radicals injury cells, leading to, among other things, premature wrinkles.

There are other reasons, too. Primary factors contributive to wrinkled, spotted skin include normal aging, exposure to the sun (photoaging) and pollution, and loss of subcutaneous support (fatty tissue between your skin and muscle). Other factors that contribute to aging of the skin include stress, gravity, daily facial movement, obesity, and even sleep position.

As you get older, however, the dermis slowly loses collagen and elastin. The fatty subcutaneous layer also loses fat over time. When these things happen, your skin gets thinner and less moisture gets to the epidermis. The epidermis will begin to sag in areas, creating wrinkles.
