Tatcha The Dewy Serum - Hydrating Serum for Smoother, Plumper, Dewy Skin | 30 ml

Meet The Dewy Serum, a clean, 3-in-1 formula designed to gently smooth the skin's surface with lactic acid from Hadasei-3, while hyaluronic acid provides a plush, plump feel and squalane helps lock in moisture for a dewy finish.

The Dewy Serum draws from a 73 percent Hadasei-3 complex, a thoughtfully fermented blend of Uji green tea, Akita rice, and Okinawa algae. This double fermentation process yields naturally occurring lactic acid and mild AHAs, supporting natural surface turnover and texture refinement without heavy polishing.

Core benefits in a single step

• Gentle resurfacing with lactic acid-rich Hadasei-3 to create a smoother texture.
• Hydration support from hyaluronic acid to help skin appear plump and comfortable.
• Moisture sealing with lightweight squalane for a dewy, lasting finish.
• Overall formula crafted to be kind to skin while delivering a radiant look.

How to use

• Apply after cleansing and The Essence, morning and or evening.
• Dispense a small amount and smooth over face, avoiding the eye area.
• Finish with your moisturizer to seal in hydration.

In real life use, the serum glides on with a silky sensation and leaves a natural, subtle glow as it sinks in. The lightweight texture supports layering in a wide range of skincare routines, from minimalist to multi-step regimens.
