Sunscreen & Antioxidants
Sunscreen alone does not block infrared radiation or visible light . When mixed with sunscreen, antioxidants are able to reduce the production of free radicals by over 75%.
When added to sunscreen, antioxidants are able to reduce the production of free radicals by up to 78% .
Resveratrol & Glycolic Acid
Resveratrol is an antioxidant found in grapes that is known to reduce pigmentation and has anti-aging properties. It inhibits tyrosinase, the key enzyme in the production of melanin.
A hybrid of glycolic acid and resveratrol, resveratryl triglycolate, has been shown to reduce sun induced pigmentation when applied twice daily for 6-8 weeks. When investigated separately, this combination of resveratrol and glycolic acid inhibited tyrosinase more effectively than glycolic acid alone .
