Aging can be broken down into two components – intrinsic aging and extrinsic aging.  Intrinsic aging is our internal biological process and genetics.  External factors are things such as pollution, UV rays, diet, toxins, chemicals and drugs.  Some scientists believe that only 3% of the way we age is related to Intrinsic aging and the remainder is basically related to the way we live our lives, diet and what we are exposed to. 

Skin aging is characterized by wrinkles, loss of elasticity and a rough textured appearance.  As we get older our skin becomes thinner, our cellular matrix contains less mast cells and fibroblasts, fibroblasts are required to produce collagen and elastin, these are two proteins found in the dermal matrix that make our skin flexible and plump.

Sleep is associated with aging skin, less than 5 hours of sleep per night may contribute to the intrinsic signs of aging. Diet and certain nutrients can have a positive effect on anti-aging.  Vitamin C is associated with reducing wrinkles, a high fat diet, refined carbohydrates, sugar and alcohol are some dietary factors that may negatively influence skin aging.  Chronic stress increases free radicals and DNA damage which may have an effect on skin aging but the exact mechanism of this action is not yet known.  Its well-known that exposure to the sun causes aging to the skin, using a chemical free face sun-cream daily can prevent damage and reduce signs of aging.
