Estée Lauder Double Wear Instant Fix Concealer is a multi-tasking dual-ended concealer that prepares the skin and also camouflages dark circles as well as dark spots and discoloration. At one end, a hydra-prep formula hydrates the skin around the eyes for a bright look and a smooth application. The 24-hour concealer side holds a long-wearing and medium to full coverage formula that erases all the imperfections you wish to conceal. Waterproof, sweat and humidity-resistant, this concealer is the ideal choice for those looking for high coverage results, that last even in hot and humid weather.The formula combines rich pigments with powerful ingredients that provide the skin with more than just good coverage. To begin with, the formula contains Argireline, a powerful ingredient that helps to minimize the appearance of wrinkles. At the same time, Hyaluronic Acid - a surface hydrator and protectant - helps water-soluble actives to penetrate deeper into the skin. In addition, Caffeine improves the microcirculation of the blood vessels in order to minimize signs of fatigue in the eye area. As a result, the skin is hydrated, perfected and embellished after each use - not only with immediate concealing but also with lasting results.
