Green Tea & EGCG

aka egcg · epigallocatechin gallate · camellia sinensis · green tea extract

Camellia sinensis polyphenols — and specifically epigallocatechin gallate (EGCG) — are among the most-studied plant antioxidants in dermatology. Photoprotective (reduces UVB-induced erythema and DNA damage), anti-androgenic in scalp/sebum contexts, and synergistic with caffeine. Youth To The People built the kale-spinach-green-tea antioxidant serum around it; The Ordinary's Caffeine + EGCG eye serum is the mass benchmark.

Benefits
  • potent antioxidant via EGCG and other catechins
  • modest topical photoprotection
  • anti-inflammatory in acne and rosacea contexts
Example uses
  • antioxidant serums (YTTP Superfood)
  • eye treatments
  • post-sun recovery
Formulation notes

Concentrated EGCG isolate (1–3%) outperforms whole-leaf extract for clinical claims. Stability is poor — pairs with vitamin E and ferulic acid for protection. Pairs with caffeine for compound antioxidant + microcirculatory effect.

Watchouts

EGCG oxidizes to brown — color change in serum = lost activity. Chinese green tea sourcing carries the same supply-transparency questions as any imported botanical.

Clean beauty perception

Strongly positive — peer-reviewed and culturally familiar.
