Source
Though commonly known to come from the skin of red grapes, Resveratrol is derived from the root of Japanese Knotweed plant which is a much more powerful and plentiful renewable source.
Science
Resveratrol is produced to increase the plant’s resistance to environmental stresses and, thus, has significant physiological and biological effects. Resveratrol promotes even skin tone by inhibiting tyrosinase, the key enzyme that catalyzes melanin production by oxidation.
Furthermore, studies have reported that resveratrol is a potent inducer of sirtuin, which activates proteins that associate with the aging process to increase longevity. A powerful antioxidant, resveratrol is also used as a free radical scavenger, photo protector, and soothing agent, as well as for anti-inflammatory action.
