Camellia Sinensis Leaf Extract

Green tea extract is a well-researched antioxidant that helps protect skin from free radical damage and UV-induced irritation, redness, and sunburn cells. Its catechins exhibit anti-inflammatory properties, making it beneficial for sensitive, rosacea-prone, and acne-prone skin, and it also demonstrates antimicrobial activity with studies showing 2% green tea lotion effective for mild-to-moderate acne. Additionally, it has anticarcinogenic properties through inhibition of UV-induced DNA damage and activation of DNA repair enzymes, particularly relevant for non-melanoma skin cancer prevention.

Efficacy is highly dependent on the polyphenol/catechin content of the specific extract used; average commercial extracts may contain as little as 10% catechins, significantly limiting their effectiveness compared to high-quality extracts (50–90% catechins).
