About this ingredient
Matcha Leaf Powder (Camellia Sinensis Leaf Powder, Matcha) is dried and finely milled Japanese matcha tea leaves. Contains a high concentration of catechins, primarily epigallocatechin-3-gallate (EGCG, 5–10%), along with caffeine, theanine, chlorophyll. Mechanism. EGCG is one of the most powerful natural antioxidants: neutralizes free radicals, suppresses matrix metalloproteinases (MMP-1, MMP-9), reduces inflammation by inhibiting NF-κB. Caffeine provides a vasoconstrictive and firming effect. Where applied. Antioxidant serums and creams, masks, eye-area products. Concentration 0.5–3%. In Spain – in niche and pharmacy cosmetics, less in mass-market lines. Evidence base. Chiu 2005 RCT (n=40) with topical 10% green tea showed reduced signs of photoaging over 8 weeks. The Hsu 2005 systematic review confirms photoprotective properties of green tea polyphenols. No standalone RCTs on pure matcha powder – evidence is extended from green tea. Safety. CIR confirmed safety of green tea extracts. Non-comedogenic, hypoallergenic. Tints skin greenish at over 2% (chlorophyll) – requires rinsing. Pregnancy and lactation – topically safe. Topical use does not lead to significant systemic caffeine absorption.
