While we may be a tad biased, we believe Tatcha products are undupable. This is due to many aspects, but mostly because our formulas have something no other dupe can claim: our proprietary Hadasei-3 complex. The name ‘Hadasei-3’ might seem unique at first glance, but it carries deep purpose and intention. In Japanese, “hada” means skin, and “sei” means "life". As for the number “3”, it refers to the foundational ingredients that power the complex: Akita rice, Uji green tea, and Okinawa algae.It’s also the definitive reason why Tatcha products cannot be duped.
The Dewy Skin Cream is difficult to replicate because of its proprietary Hadasei-3 complex - a blend of Akita rice, Uji green tea and Okinawa algae, inspired by traditional Japanese fermentation.
Double-fermented with a proprietary yeast, Hadasei-3 is rich in lactic acid, amino acids, antioxidants and nutrients. Rather than simply adding it as an ingredient, Tatcha incorporates it into the formula’s water phase to help hydrate and nourish skin. It’s this proprietary complex, combined with Tatcha’s formulation expertise, that makes The Dewy Skin Cream truly unique.
