Do antioxidant JUST protect skin cells to prevent aging, or can they actually rair damage?

Basically anti-oxidants are preventative for aging…
To use non-sciencey terms they kind of neutralise or counter the bad aging causing chemicals called ‘free-radicals’
free radicals cause wear and tear of cells – anti-oxidants prevent this
hope this helps

good sources of anti-oxidants are
green tea
TOMATOES!!!!

I saw this show on CNN about this antioxidant, anti-aging product called
resveratrol that is a part of the red grapes that has been isolated and scientists are saying that it is great to protect from heart disease and is an anti-aging agent. Anyone have any experience with this and know where to buy the best kind?

Any health or vitamin store.
