COSRX Advanced Snail Mucin Glass Glow Hydrogel Mask is a hydrogel face mask, saturated with a deeply restoring essence with as much as 25% mucin. Snail mucin is an extremely valuable cosmetic ingredient, famous for its regenerating, brightening, moisturizing and skin-soothing properties, helping to restore skin elasticity and natural radiance. The formula also combines low-molecular collagen, which improves skin tone and firmness, niacinamide, a strong antioxidant that evens out skin tone and slows down aging processes, and betaine, which has a soothing and regenerating effect. The ceramide complex strengthens the skin's protective barrier and helps retain moisture for longer, making the skin smoother, softer and more resistant to external factors. Due to the hydrogel texture, the mask gradually becomes transparent, and its active ingredients are absorbed deep into the epidermis. It is divided into two separate parts, so it fits perfectly to the contours of the face, allowing you to move and perform daily tasks for even several hours, while maintaining maximum efficiency.
