COLLECTION: Aquaporin Active / Eucerin AQUAporin ACTIVE for normal to combination skin is a refreshing facial moisturizer that enhances the skin's natural hydration system and leaves skin supple, soft and radiant. Our skin needs water to perform its functions efficiently. Well-hydrated skin is soft and smooth and looks radiant. When the skin's natural protective barrier is weakened, it loses moisture and becomes dehydrated. Dehydrated skin looks dull, feels tight, cannot keep out external irritants and becomes sensitive. Intense, long-lasting hydration is necessary for skin to look and feel good. To improve skin hydration, most moisturizers prevent excessive evaporation of water from the skin or retain moisture in the outermost layer of the skin with humectant ingredients, such as Glycerin. The skin has its own hydration system: the Aquaporins. These channels transport water between skin cells and support skin hydration from within. Eucerin AQUAporin ACTIVE enhances the skin's natural resistance. Its formula contains Glucoglycerol, a state-of-the-art moisturizing active ingredient that has been proven to increase the amount of Aquaporins in the skin. This means that in addition to limiting water evaporation and retaining water in the surface layers of the skin, Eucerin AQUAporin ACTIVE products enhance the skin's natural moisturizing system. The light and refreshing texture of Eucerin AQUAporin ACTIVE for normal to combination skin provides intense moisture for 24 hours and is easily absorbed. It relieves the feeling of tightness and leaves the skin soft and supple. Eucerin AQUAporin ACTIVE is clinically and dermatologically tested for compatibility with sensitive skin and is free of perfumes and parabens.
