Consuming a diet rich in vitamins and antioxidants and applying topical products containing these ingredients can protect the skin from damage caused by the sun and may even help reverse some of the effects of sun damage.
Free-radicals are molecules that “steal” electrons from healthy skin cells. This can interfere with the cells’ functioning and slow down the regeneration process, contributing to wrinkles and aging. Free-radicals come from pollution and the sun’s UV rays. Antioxidants attract free-radicals and bind with them, which prevents them from damaging skin cells.
Vitamins C and E and selenium are antioxidants that can protect the skin from sun damage and skin cancer. They may even reverse discoloration and wrinkles associated with aging by speeding up the skin’s repair systems and preventing further damage. Taking vitamin C, vitamin E, and selenium supplements can protect your skin from sun damage.
Coenzyme Q10 (CoQ10) is an antioxidant that occurs naturally in the body and protects it from cancer. A natural drop in CoQ10 occurs with age and leads to wrinkles. A study found that applying CoQ10 directly to the skin can reduce the effects of aging. Most studies that have been conducted used a 0.3% concentration.
Alpha-lipoic acid is another antioxidant that can combat aging. Studies in which participants applied creams with 3 to 5% concentrations every other day and gradually increased to every day improved the appearance of their skin.
Retinoic acid is the active form of vitamin A in the skin and can reduce fine wrinkles, age spots, and rough skin when applied topically. It restores the elastic fibers that keep the skin taut. It can be applied in the form of a gel or cream with a concentration ranging from 0.01 to 0.1% applied every second or third night at first and eventually every night.
Green tea and chocolate contain flavonoids, which studies have shown can protect the skin from cancer and inflammation. Benefits can be derived from drinking green tea, applying green tea extract topically, eating chocolate, and drinking hot cocoa.
B vitamins found in chicken, eggs, and fortified grain products can protect the skin. They can also provide benefits when applied directly to the skin.
Other plant-based extracts, such as rosemary, tomato paste (lycopene), grape seed extract, pomegranate, and soy, can protect the skin when ingested or applied topically. Some scientists believe a blend of different antioxidants is better than a single product.
Some products are advertised offering miraculous results, but these claims may not be backed up by scientific studies. It may also be difficult to know if vitamins and antioxidants are in the right concentrations to be effective. Talk to your dermatologist before you try a product with vitamins or antioxidants for your skin.
