Americans spent more than $7 billion in 2008 on skin products to prevent aging, according to the American Academy of Dermatology, or AAD. Hundreds of products on the market claim to prevent, minimize or eliminate wrinkles, age spots and other signs of aging. Look for products with ingredients scientifically proven to reduce or prevent aging. The AAD recommends using one product at a time to reduce the risk of skin irritation.
Sunscreen
The AAD explains that sunscreen is the most beneficial antiaging product available. Just a few minutes each day over years of unprotected exposure to the sun's rays is enough to cause noticeable damage later in life. Daily use of sunscreen prevents sun damage such as wrinkles, age spots and thick skin. It may also help repair existing damage. Look for an SPF 30 or higher broad-spectrum sunscreen that blocks both UVA and UVB rays. Be sure to reapply the sunscreen every few hours if you are outside for a long time.
Alpha Hydroxy
Alpha hydroxy acids are synthetic versions of acid derived from fruits that contain sugar. These acids work by removing the dead top layers of skin. A study performed by the Department of Dermatology at the Hahnemann University School of Medicine in Philadelphia found that significantly decreased skin thickness and reversed signs of aging related to sun damage. The results of this study were published in the February 1996 issue of the Journal of the American Academy of Dermatology. Alpha hydroxy acids can increase the risk of sunburn.
Retinol
Skin products containing retinol, derived from vitamin A, can reduce the appearance of wrinkles and lines by peeling off the top layer of skin, explains the New Zealand Dermatological Society. A 1999 study performed by the Department of Dermatology at the National University of Athens found that the aging effects of the sun can be reversed by topical retinoid. Retinol products increase sun sensitivity and may cause peeling, irritation or redness. Avoid contact with eyes and mouth.
Vitamin C
Results of a 2003 study performed by the Department of Dermatology at the University of Franche-Comté in France suggest that topical skin creams containing 5 percent vitamin C improves sun-damaged skin by repairing damaged tissue and decreasing deep furrows. Vitamin C has antioxidant properties and aids in the production of collagen, the fiber that helps give skin its elasticity. University of Maryland Medical Center explains that topical vitamin C combined with collagen-boosting madecassoside may significantly improve wrinkles and skin texture.
