Camellia Sinensis Leaf Extract (91.7 Ppm)
Camellia Sinensis Leaf Extract is derived from the leaves of the tea plant (Camellia sinensis, Theaceae) and is commonly known as green tea extract. Its key active components are polyphenols, specifically catechins, with EGCG (EpiGalloCatechin Gallate) being the most abundant and active. Quality varies significantly between extracts depending on growing conditions and processing; high-quality extracts contain 50–90% catechins and are typically brownish with a characteristic odor. It is listed under CAS # 84650-60-2.
Green tea extract is a well-researched antioxidant that helps protect skin from free radical damage and UV-induced irritation, redness, and sunburn cells. It exhibits anti-inflammatory properties beneficial for sensitive, rosacea-prone, and acne-prone skin, and shows antimicrobial activity with studies supporting efficacy of 2% green tea lotion for mild-to-moderate acne. It also demonstrates anticarcinogenic potential by inhibiting DNA damage and supporting DNA repair, particularly relevant for non-melanoma skin cancer prevention.
Efficacy is highly dependent on the polyphenol/catechin content of the specific extract used; low-quality extracts with only ~10% catechins may provide significantly reduced benefits. No specific contraindications are noted in the source.
