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.
