Green Tea Extract (EGCG)

Green Tea Extract (EGCG) — an antioxidant-rich botanical extract derived from the leaves of Camellia sinensis, whose most studied active compound is the polyphenol epigallocatechin gallate (EGCG). Used topically, it is prized for its antioxidant and soothing properties that help calm the look of stressed skin and defend against environmental damage.

Key points

  • Green tea extract is a source of catechins, with EGCG being the most abundant and biologically active polyphenol.
  • Its antioxidant activity helps neutralize free radicals generated by UV light and pollution.
  • Studies indicate it has soothing, skin-calming properties that can help reduce the appearance of redness and irritation.
  • It is often included in daytime formulas and can complement sunscreen, though it is not a replacement for SPF.
