This beauty treatment is very popular with citizens in France and stars like Cindy Crawford, Rihanna and others who use vitamin and antioxidant drips for the same effect.  Grape seed supplements have been shown to boost antioxidant levels in the blood. They also protect collagen and elastin in the skin, which makes your skin stronger, firmer, and more elastic. Keep in mind that you would need to get actual grape seed extract supplements, as you would have to eat up to 50 pounds of regular grapes to get the same effect.
