5 Weeks of using the @Tatcha Brightening Line I used the Brightening Serum and the Brightening Eye Cream morning and night for 5 weeks. Both products have a unique 12-hour time release vitamin C that felt gentle on my skin! I usually have an issue with vitamin C being so irritating but LOVED these products! The texture of the serum was light and not-sticky. It almost felt like an essence. This is great for all skin types including sensitive skin! If you are looking for gentle products that leave you with visibly brighter, firmer skin then these are for you! Shop Tatcha’s Brightening Line online and in-store at @sephora #Tatcha #TatchaPartner
