Resveratrol is a naturally occurring polyphenol sourced from grapes, berries, and Japanese knotweed. In cosmetics it's used for antioxidant support, formula stability considerations, and to support skin's look under environmental stress.

Our take
Is Resveratrol a Good Ingredient?
Good, because it's a well-studied antioxidant that helps buffer oxidative stress, though clinical outcomes in leave-on products are modest and it can degrade without protective packaging or co-antioxidants. It works best as part of a blend rather than carrying a formula on its own, which keeps it from Great.
What it does
Skin Benefits
Helps skin look brighter and more resilient by neutralizing everyday oxidative stress, and may reduce the look of early fine lines and redness for a calmer appearance.

Before you use it
Safety
Generally well tolerated with a low irritation profile, but higher concentrations or alcohol-heavy formulas can cause transient sensitivity in some users. Patch test if you have reactive skin.
