Smooth Diamond Collagen Peel-Off Mask is a treatment that uses a gel-like formula containing collagen and often diamond powder to exfoliate the skin, physically remove dead skin cells and impurities, and promote a smoother, brighter, and more radiant complexion. The mask dries to form a film that is then peeled off, revealing fresher skin and potentially diminishing the appearance of fine lines and wrinkles while improving skin's texture and elasticity.
