Designed to reinvigorate fatigued-looking skin, the 111SKIN Sub-Zero De-Puffing Energy Facial Mask helps to reduce puffiness and encourages a more refined appearance. Supercharged by tetrapeptide-5 and alpha glucosyl hesperidin, these refreshing two-piece hydrogel face masks are inspired by cryo-therapy. Providing cooling hydration, they de-puff your face while supporting skin's overall firmness. What's more, with an invigorating infusion of caffeine, they increase blood microcirculation, minimise the appearance of dark circles, inhibit collagen breakdown and tighten your visage. If you love the cooling sensation, we suggest keeping them in the fridge, for an added dose of chill. How To Use Cleanse skin thoroughly. Remove Mask 1 from protective film and apply onto the top half of the face. Follow with Mask 2 and apply onto the lower half of the face. Leave on for 20 minutes. Remove the mask and let the skin absorb the remaining essence by gently patting the skin. Follow with your regular skin regime. Recommended use: For optimum results use three times a week.
