About the Product

This sheet mask combines niacinamide and glutathione to help even out skin tone and boost radiance. Niacinamide is a form of vitamin B3 that supports barrier function and helps fade the look of dark spots, while glutathione is a powerful antioxidant that works alongside it for brightening. Each mask is soaked in a concentrated essence that delivers these ingredients directly to your skin.
