Deeply quench your dry skin for an extra-smooth, supple complexion with Neutrogena Hydro Boost Hyaluronic Acid Serum. Suitable for all skin types and for use on sensitive skin, the daily face serum layers underneath your moisturizer to instantly refresh dry skin by infusing weightless moisture deep within your skin's surface. Proven to smooth skin and hydrate for 24 hours, the dermatologist-tested, daily face serum is formulated with 17% Hydration Complex and contains both high & low weight hyaluronic acid, an essential hydrator naturally found in skin, absorbing and holding water to the skin. The skin-mimicking water-magnet trehalose joins with dermatologist-recommended glycerin, which penetrates nine layers deep within the skin's surface. The hydrating face serum is hypoallergenic, non-comedogenic, and free of fragrance, parabens & mineral oil. Apply 4-5 drops of this lightweight hyaluronic acid serum after cleansing and before moisturizing, as part of your at-home skincare routine.
