Our Science

We believe the body is brilliant at healing itself. The geisha recognized that to maintain baby-soft skin, one must replenish and enhance the skin’s natural protection against environmental stresses. This allows skin to heal itself and return to its native balance and optimal beauty.

TATCHA recreates the geisha’s minimalist beauty regime with fresh preparations of concentrated bioactive materials, accessing their active ingredients through a proprietary extraction process of Green Tea, Okinawa Red Algae and Rice Bran.

HADASEI-3 Bioactive Complex—a proprietary anti-aging complex of:

• Green Tea Complete DNA Extract—extremely rich in EGCG, 14 times more potent than traditional green tea extracts and 5 times more potent than Vitamin C in protecting against UV-induced oxidative damage, which is a leading contributor to premature skin aging.

• Okinawa Red Algae Extract—a vital source of Beterhelin, a natural polysaccharide proven to enhance the skin’s barrier function for long lasting moisture retention and texture improvement. Shop TATCHA  bestsellers containing Red Algae. >

• Japanese Rice Bran Extract—prized for centuries as a rich source of inositol, a multitasking active which is at once a powerful anti-oxidant and nourishing moisturizer. Shop TATCHA bestsellers containing Rice Bran. >

Together, these time-tested ingredients enhance the skin’s natural beauty, promote nourishing moisturization and help reduce the signs of premature aging for truly pure, polished, radiant and supple looking skin.
