Antioxidants are compounds that help neutralize free radicals, which are unstable molecules that can damage cells and contribute to signs of aging and skin damage. Common antioxidants used in skincare include vitamins C and E, coenzyme Q10, green tea extract, resveratrol, and niacinamide. These ingredients are often found in serums, moisturizers, and other skincare products designed to combat signs of aging, protect against environmental damage, and promote overall skin health.
