Green tea extract is a polyphenol-rich botanical with real antioxidant and anti-inflammatory activity, largely associated with catechins such as EGCG.
Human and experimental studies support topical photoprotective biology against UV-induced oxidative and inflammatory stress. It does not replace sunscreen, but it can be a meaningful antioxidant partner in a formula.
Usage & cautions
Usually well tolerated. It is supportive photoprotection, not an SPF substitute.
Information approach
Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
