Antioxidants protect cells from unstable molecules that can cause damage to healthy cells, on the skin and in the body , according to the National Cancer Institute. Two of the most famous antioxidants are vitamins E and C. Grape seed extract contains several plant compounds , including oligomeric proanthocyanidins ,or OPCs . OPCs are powerful antioxidants , and according to a report from the Food Research Center in Guelph , Canada , OPCs in grape seed extract contain 20 times the antioxidant power of vitamin E and 50 times the antioxidant power of vitamin C. The report , published in the Winter 2003 issue of "Journal of Medicinal Food ," states that grape seed extract can protect the body from sun damage . The sun can damage skin by causing wrinkles , pigment changes and skin cancer.
Protecting the skin from sun damage will maintain, or improve, the overall appearance of the skin. Researchers in the "Journal of Medicinal Food " report claim that grape seed extract benefits the skin's appearance by bonding with collagen ,which is the building block of healthy skin , maintaining skin cell health as well as the skin's elasticity .The antioxidant power of the OPCs in grape seed extract is credited for these benefits as well . A paper from Vanderbilt University in Tennessee explains the process by which antioxidants, or OPCs , protect and improve skin appearance . Free radicals , which are molecules that damage healthy cells, have an unpaired electron. To make up for this lack, the free radical will try to steal an electron from healthy protein in the skin. When this happens, it sets off a chain reaction, because the healthy cell that was stolen from is now a damaged cell, and looks to steal an electron from another cell. What this leaves behind is a chain of damaged molecules, and the skin's cellular structure is now weakened. The antioxidant power of grape seed extract fights the free radicals, and protects the skin from damage. Free radicals can develop as a result of sun damage, pollution, cigarette smoke and even stress.
Chloasma, also known as melasma, is a condition in which the pigmentation of the facial skin appears brown and blotchy. Chloasma can develop as a result of hormonal fluctuation, sun exposure, a toxic reaction to cosmetics or for no known reason at all, according to the New Zealand Dermatological Society. Regardless of the cause, chloasma can cause embarrassment if you are suffering from it. Medical treatment for chloasma can involve painful dermabrasions or costly, and toxic, medications. However, grape seed extract has also been found to treat chloasma, and it is a natural, safe alternative. A study published in the November 2004 issue of "Phytotherapy Research" showed that after six months of treatment with oral grape seed extract, chloasma significantly improved.
