Anti-Aging & Antioxidants in Houston Dermatology

Last time we discussed the importance of antioxidants in caring for the skin and using topical antioxidants in addition to daily sunscreen.  Resveratrol is an antioxidant that has proven in clinical studies (over several years) to significantly reduce free radicals. Foods containing resveratrol include peanuts, cocoa, grapes and berries.  For resveratrol to work best, it is beneficial to apply it topically before UV exposure.  The mechanism of action is resveratrol’s unique ability to inhibit production of hydrogen peroxide radicals and lipid peroxidation, and other radicals.  Green tea is another powerful antioxidant called a polyphenol.  Natural properties of green tea make it an excellent antioxidant and anti-inflammatory.  Results from clinical research show that components of green tea (epigallocatechin gallate, or EGCG)) applied either before or immediately after UV exposure are able to prevent cellular damage and provide protection from further damage to the skin.  Another excellent antioxidant is genistein, which is an isoflavone from soybeans.  Genistein is special because it has the ability to not only short-term damage from UV exposure, but also long-term damage from UV exposure including visible photoaging, redness in the skin caused by capillaries (i.e., erythema), and certain carcinomas.  There are other important and powerful antioxidants besides Resveratrol, green tea, and genistein, but they are major ones with respect to the skin.  West Houston Dermatology, in addition to medical dermatology services, offers anti-aging treatment and products that are carefully evaluated using medical criteria.
