When it comes to plant derived antioxidants in dermatology, green tea extract is among the most extensively studied. Its strength comes from polyphenols, especially epigallocatechin gallate, or EGCG, which deliver both antioxidant and soothing effects. Applied topically, green tea has been shown to offer a range of anti aging benefits and, notably, to meaningfully improve the look of sun damaged skin.
On an ingredient label, you'll typically see it listed under its Latin name, Camellia sinensis or Camellia oleifera. Gentle enough for regular use yet backed by a substantial body of research, it's one of the more reliably impressive antioxidants in skincare.

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.
