C Gel

Since ascorbic acid reacts to water and turns useless, this one is suspended in an anhydrous formula, meaning there's no water. Being water-free, this 20% formula won't mess with the pH of your skin and stay stable until the very last glob. The supporting cast of ferulic and hyaluronic acid makes the vitamin C last longer - and work better. Apply the product on dry skin as the first step after cleansing. Gently pat in the product till it is completely absorbed. Avoid layering heavy exfoliating treatments.
