Resveratrol Description
Resveratrol belongs to a class of plant compounds called stilbenes, produced by grapevines and a handful of other plants as a natural defense against fungal infection and UV stress. It's the same compound behind the "French paradox," the observation that red wine drinkers seemed to have lower rates of heart disease, which is originally what put resveratrol on researchers' radar before its skin benefits were ever studied.
One of its most interesting mechanisms is its ability to activate SIRT1, an enzyme belonging to a family called sirtuins that helps cells respond to stress and has been linked to longevity in lab research. In skin specifically, resveratrol has been shown to inhibit UV-induced oxidative and mutagenic damage to skin cell DNA, a more targeted mechanism than simply mopping up free radicals after the fact. It also appears to influence enzymes involved in how the body processes and clears out damaging compounds, adding another layer to its protective effect beyond basic antioxidant activity.

Ingredient Ratings
Our team reviews ingredient research and uses up-to-date evidence to rate ingredients based on the categories below.
Best
Ingredients with the most rigorous and convincing evidence. These are the standouts backed by consistent findings across independent, peer reviewed clinical research.. When we call an ingredient Best, it has earned that distinction through genuine, reproducible proof that it improves skin.
Good
Reliable, well tolerated ingredients that do their job without complaint. They may not carry the headline benefits of a Best rated active, but they hydrate, stabilize a formula, or support the ingredients around them in ways that make a real difference in how a product performs and feels.
Average
Ingredients that are perfectly safe and serve a clear function, typically as an emollient, thickener, or filler, but do not offer any meaningful skin benefit beyond that basic job. Not a red flag, just not a reason to choose one product over another.
Bad/Worst
Ingredients with documented potential to irritate skin, disrupt the barrier, or trigger sensitization in some users, often synthetic fragrance, drying forms of alcohol, or certain essential oils. Not automatically a dealbreaker for every skin type, but worth knowing about before you commit to a product.
