Like a double espresso for your (all too fragile) under-eye area, THE INKEY LIST’s Caffeine Serum harnesses the anti-inflammatory, antioxidant powers of coffee to bring them to your skin. Soothing and protecting this delicate area of your face, Caffeine Serum helps to reduce puffiness, minimise dark circles and prevent the skin damage that can be caused by free radicals – these can make dark circles more pronounced. As caffeine is a diuretic, it can help to relieve water retention, which can be a major cause of pesky puffiness under your eyes. Also enhanced with renowned age-defying peptide, Matrixyl 3000, the formula helps to boost collagen production and so minimise fine lines and wrinkles around your eyes.
