Researchers now know that aging skin is the result of more than just chronological age.  Everyday your skin is exposed to environmental elements like sunlight, smoke, and air pollution - elements that cause oxy radicals to form in the skin.  These oxy radicals attack the skin's collagen layer and break it down, causing lines and wrinkles to appear.  This process is commonly called photo-aging.

Clinical evidence shows that precise applications of anti-oxidants can help prevent photo-aging in skin.  Recent research conducted by Dr. Sheldon Pinnell at Duke University Medical Center shows that applying vitamin-C to the skin can:

• Provide anti-oxidant protection
• Prevent photo-aging
• Stimulate collagen production

However, not all vitamin-C formulations can produce these benefits. Dr. Pinnell's studies show that in order to be effective, a vitamin-C formulation must contain several precise characteristics.

• It must contain L-ascorbic acid. L-ascorbic acid is the only form of vitamin-C that can be used by the body.
• It must be formulated at acid pH, otherwise the vitamin-C will not be absorbed by the skin.
• It must contain at least a 10% concentration of vitamin-C.
• It must be stable.
