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. It has very strong peroxyl radical scavenging abilities, more than gallic and ellagic acids and epicatechins. Resveratrol has been shown to protect against UVB mediated skin damage in mice by boosting anti-oxidant defenses, and it has been shown to help alleviate skin wounds.
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 to be found in the dermis and epidermis. It has been shown to preserve dermal collagen, and may be effective in enhancing glycosaminoglycans, which enhance tissue hydration. It has been shown to stimulate skin’s cellular renewal, and help increase skin’s 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 a significant inhibition of growth over time. It also inhibits keratinocyte proliferation, which contributes to the formation of acne lesions.
Our Resveratrol Pure is extracted from the root of wild-crafted Japanese Knotweed (Polygonum Cuspidatum) using only ethanol and water. It is then vacuum dried, micronized and standardized to a 99% concentration of trans-Resveratrol in its final form. It has an average particle size of 3-4 microns.
