Our Journey to You

Our journey began when Vicky Tsai traveled to Japan and encountered a philosophy of care that helped her rediscover love for her skin and for herself. A decade of working in the corporate world had left her disillusioned, and suffering from dermatitis that required daily steroids and antibiotics. Through timeless rituals rooted in effective yet gentle Japanese ingredients, her skin and her life regained balance. Alongside a team of scientists, geisha, and cultural advisors from Tokyo to San Francisco, Tsai created Tatcha to share these caring rituals with you.

Our Proprietary Complex: Hadasei-3™

At the heart of the Tatcha collection lives a tiny symphony of superfoods called Hadasei-3. This proprietary complex of twice-fermented rice, green tea, and algae is rooted in the nutrient-dense Japanese diet, largely considered the healthiest in the world.

Through the power of fermentation, these three superfoods help reveal soft, plump skin with a healthy-looking radiance. With naturally moisturizing proteins, Akita rice supports healthy moisture barrier function. Rich in antioxidants, Uji green tea neutralizes oxidative stressors and visibly reduces signs of premature aging. Packed with skin-plumping polysaccharides, Okinawa algae improves skin’s ability to retain moisture. As a by-product of our specialized fermentation process, Hadasei-3 contains essential amino acids and gentle AHAs like lactic acid to gently resurface as it hydrates.
