Resveratrol

INCI: Resveratrol

Resveratrol, a polyphenol found in Japanese Knotweed and the skin of red grapes, is a very effective anti-oxidant with 95% efficiency in preventing lipid peroxidation as compared with 37% for Vitamin C or 65% for Vitamin E. Resveratrol is effective against photoaging due, in part, to its anti-oxidant properties, and is recommended for use in pre-or post-sun exposure products.

Resveratrol can pass through the stratum corneum in the dermis and epidermis. It has been shown to preserve collagen and may effectively enhance glycosaminoglycans, which improve tissue hydration. It has been shown to stimulate skin’s cellular renewal and help increase skin thickness. And it has been shown to inhibit tyrosinase, which indicates its use for reducing hyperpigmentation.

Resveratrol has shown anti-fungal and anti-bacterial activity and has been included in products intended for diabetic wound care. It demonstrates sustained bacterial activity against P. acnes, the bacteria that causes acne. Whereas benzoyl peroxide showed a short-term bacterial response, resveratrol showed significant growth inhibition over time. It also inhibits keratinocyte proliferation, which contributes to the formation of acne lesions.

It's important to note that the color of resveratrol can vary from white to a very light pinkish depending on the season and pigment content of the knotweed from which it is extracted.
