Aging is characterized by the loss of collagen and elastin, decline in circulation, decrease in repair of damaged tissue, increase in scar tissue deposits, slowing of epidermal turnover, damage to DNA and increased MMP (enzymes that break down collagen and elastin) activity.
One of the biggest contributors to the formation of premature wrinkles is UV exposure. Chronic UV exposure is the cause of many types of Skin Cancers and pigmentation disorders. It causes premature aging by thinning the epidermis as well as causing breakdown of collagen, elastin and a decrease in GAG (Glycosaminoglycans) formation.
A second major contributor is expression lines. These are wrinkles that are caused by muscle contractions (facial expressions). This leads to the compression and folding of the skin layers resulting in wrinkle formation. Initially these wrinkles only appear when the muscle contracts, however, as the skin ages these folds become more prominent and appear when the muscles are at rest.
The treatment strategy for Aging includes increasing the skin’s antioxidant and food supply, stimulation of collagen and elastin, removal of scar tissue, increasing epidermal turnover, normalizing moisture and oil levels and improving the skin’s UV protection.
