The Art of a New Start
Inspired by the Japanese concept of shinsei, which translates to ’new birth,’ our Chief Scientist at the Tatcha Institute in Tokyo, Tagawa-san, created The Dewy Serum to restore and replenish the key components of healthy skin, lost over time, to help it perform at its optimal level. Our proprietary complex, Hadasei-3™, gently resurfaces, and as dead skin cells are washed away, the serum replenishes with two substances native from birth—plumping hyaluronic acid and moisture-locking squalane. Together, these three ingredients return to your skin the supple, bouncy radiance lost over time.
Featured Ingredients
Lactic Acid & Gentle AHAs in Hadasei-3™: Our proprietary complex of Japanese superfoods Uji green tea, Akita rice and Okinawa algae comprises 73% of The Dewy Serum. The three superfoods are given new life through a double fermentation process that generates high levels of naturally-occurring lactic acid and gentle AHAs that promote natural skin surface turnover, smoothing the look of lines and improving texture.
Hyaluronic Acid & Sugarcane-derived Squalane: Hyaluronic Acid is a polysaccharide that naturally occurs in the skin. This moisture-binding molecule helps skin retain moisture for a hydrated, plump appearance. Sugarcane-derived Squalane is a saturated and stable hydrocarbon naturally found in the skin, which works as a humectant to seal in moisture and keep skin hydrated throughout the day.

I am LOVING all of my Tatcha skin care!! I’ve been waiting to try these products for a while. Honestly I was sold when I tried the Pearl and the Silk Canvas. These products have truly balanced my combination to dry skin. Living in Philadelphia we have extremely cold winters and hot, humid summers. This product brings a healthy, hydrated, moisturizing balance to the skin with a healthy glow. I highly recommend this to everybody! Thank you TATCHA👑💜

I have been unhappy with my skin and now that I’ve switched to Tatcha products I really see an improvement. Buy the product again.
