Resveratrol is a compound found in red grapes, mulberries, peanuts, and certain plants, used medicinally as an antioxidant and anti-inflammatory.

The antioxidant has twice the antioxidant benefit of resveratrol, found in red wine.

According to dermatologist Leslie Baumann, red wine contains skin-friendly grape-seed extract and resveratrol, two powerful antioxidants.

No one knows exactly how resveratrol works, but scientists believe it activates a wide range of genes, creating a cascade-like effect on a variety of body functions.
