Review: You need to try this product! - This is the most remarkable product. It works on all types of skin. It makes my skin look and feel soft and hydrated. My skin looks forward to the serum daily. I wear this regardless of the type of foundation that I use. My skin tends to be more sensitive to beauty products and this serum is very soothing and I don't react to it.
Review: I finally found my match. - This product really does soften my 67 year old skin. I’m very pleased with it because it doesn’t irritate the eczema on my face.

## Features

- A 3-IN-1 SERUM of clean, kind-to-skin ingredients that gently resurfaces with lactic acid in Hadasei-3, plumps with hyaluronic acid, and locks in moisture with squalane for smoother, plumper, dewier skin.
- 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.
- A 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.
- Use The Dewy Serum during your morning and/or evening skincare ritual. Ideally, it should be applied following The Essence and before your moisturizer to amplify its results.
- BEAUTIFUL FACES, BEAUTIFUL FUTURES: Every Tatcha purchase supports education equality worldwide. In 2014, we created this fund to help girls stay in school through the Girl’s Education Program in Asia and Africa. As of 2021, your purchases also bring diverse books to underserved communities in the United States through Room to Read’s U.S. Literacy Initiative.
