Niacinamide Sheet Mask contains soothing niacinamide which helps control sebum and counter impurities. Niacinamide is an active form of vitamin B3 with a good effect on large pores, fine lines and uneven skin tone. Niacinamide also has anti-inflammatory properties that calm down and counteract acne. Niacinamide strengthens the skin's elasticity and helps the pores contract and appear smaller. This happens because niacinamide affects how often the important enzymes NADH and NADPH are broken down in the cells. NADH and NADPH are involved in many processes in our cells, including the production of collagen and the lipids that support the skin's barrier function, which is what makes the skin stay elastic.Use:1. Thoroughly wash and gently wipe your face. 2. Unfold the mask and apply on your face. 3. Remove the mask after 10-20 minutes and let the skin absorbe the remaining essence by gently patting the skin. 23 g The Lab Performance Niacinamide Sheet Mask
