Uji Matcha: What It Does for Your Skin
Uji matcha is powdered green tea (Camellia sinensis) from the Uji region of Kyoto, Japan's historic premier matcha region. DAMDAM confirms on-site that its tea leaves are harvested from Uji, and uses Camellia sinensis leaf extract in its Matcha Boost Eye Serum.
What has matcha been studied for on skin?
Camellia sinensis leaf extract, the same form DAMDAM uses, has been studied in a topical human study for skin hydration and barrier function (Shill 2025). A topical green tea polyphenol extract has been studied for skin elasticity (Wisuitiprot 2022), and green tea catechins, chiefly EGCG, have been studied in laboratory models for antioxidant activity. Matcha reads best as an antioxidant-rich botanical that helps protect skin against everyday environmental stress. It is not a sun-protection ingredient, and no SPF claim is made.
What are Dual-Phase Oxidation Inhibitors?
DAMDAM describes the antioxidants in its Uji matcha as Dual-Phase Oxidation Inhibitors, its own term for how it positions matcha's antioxidant role in the Matcha Boost Eye Serum. It is a brand formulation description rather than a proven delivery mechanism, and it carries no sun-protection meaning.
Why does the Uji region matter?
Uji has been Japan's leading matcha-growing region for centuries and is closely tied to the tea ceremony (chado). That provenance is the heart of the story; the farm name is held with the client, and the region-level origin is what DAMDAM confirms on-site.
