Eucerin AQUAporin ACTIVE for Dry Skin is an innovative facial moisturizer that boosts the skin's own moisture system to leave it supple, soft, and radiant. Skin needs water to function efficiently and effectively. Well-hydrated skin is soft, supple, and radiant. When the skin's natural protective barrier is compromised, it loses its natural moisture and becomes dehydrated. Dehydrated skin looks dull, feels tight, and can't protect against external irritants. The result is sensitive skin. Intense, long-lasting hydration is necessary to keep skin looking and feeling its best. Most moisturizing products improve skin hydration by limiting water evaporation and/or locking moisture into the outer layer of the skin with humectants such as glycerin. The skin also has its own moisture system: aquaporins. These are microscopic channels that transport water between skin cells and boost the skin's moisture system from within. Eucerin AQUAporin ACTIVE boosts your skin's natural strength. The formula contains glucoglycerol, a newly developed moisture-enhancing ingredient, which has been shown to increase the number of aquaporins in the skin. This means that, in addition to limiting evaporation and binding water to the skin's outer layers, Eucerin AQUAporin ACTIVE boosts the skin's own moisture system. The velvety texture of Eucerin AQUAporin ACTIVE for dry skin provides intense 24-hour moisture as it is rapidly absorbed into the skin. It relieves tightness and leaves skin feeling soft and supple. Eucerin AQUAporin ACTIVE is clinically and dermatologically tested for compatibility with sensitive skin and is fragrance- and paraben-free.
