Encourage luminous, firmer-looking skin with Perricone MD’s Cold Plasma+ Treatment Sheet Mask. The concentrated mask features two separate components that adapt seamlessly to the contours of the face, delivering a burst of hydration and visible radiance. Vitamin C ester, a potent and highly stable form of vitamin C, works to improve the look of the skin tone, while copper tripeptides encourage the illusion of a collagen-rich complexion. Complete with moisturising phospholipids, the mask helps to leave skin feeling invigorated.
