Works up to 11x faster in the skin than classic forms of retinol. This ground-breaking night serum cream firms, plumps, and resurfaces the skin, visibly minimising the appearance of fine lines and wrinkles to deliver a healthier, more youthful, even-toned complexion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFine Lines \u0026amp; Wrinkles\u003c\/li\u003e\n\u003cli\u003eAnti-Wrinkle\u003c\/li\u003e\n\u003cli\u003eSmoothing\u003c\/li\u003e\n\u003cli\u003eBrightening\u003c\/li\u003e\n\u003cli\u003eFirming \u0026amp; Tightening\u003c\/li\u003e\n\u003cli\u003eReduces Pigmentation\u003c\/li\u003e\n\u003cli\u003eRegenerative\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to use:\u003c\/strong\u003e After cleansing in the evening, blend a small amount over face and neck before your regular Medik8 hydrator.
