Resveratrol

Resveratrol is a polyphenolic stilbene compound naturally found in grape skins, Japanese knotweed, and certain berries, renowned for its potent antioxidant and anti-aging properties. This ingredient has gained significant attention in cosmetics for its ability to activate sirtuins (longevity proteins), neutralize free radicals, and provide anti-inflammatory benefits that help protect skin from environmental stressors and photoaging. The micronized powder form enhances its stability and dispersibility in formulations, though resveratrol remains sensitive to light and oxidation, requiring careful formulation with appropriate stabilizers and packaging.
