Get ready for a hydration marathon with DermDoc Hydrating Sheet Mask infused with Ceramides. Naturally produced by the body, Ceramides are lipids that help form the skin's barrier and help skin retain moisture. Ceramides protect the skin against environmental aggressors like irritants and pollution. Although ceramides are produced naturally by the skin, they may be depleted by exposure to hot water, soaps, certain chemicals and other environmental factors. Replenish your skin with DermDoc Hydrating Sheet Mask infused with Ceramides. Made with super refined viscous fibre, this Sheet Mask adheres to the face like second skin and enables the active ingredients & other nutrients to be effectively delivered.
