Hydrate and refresh dull, dry skin with Neutrogena Hydro Boost Hydrating Hyaluronic Acid Serum. This lightweight, oil-free facial serum quenches skin on contact and delivers long-lasting hydration for a supple, glowing complexion. Formulated with purified hyaluronic acid—a dermatologist-recognized hydrator naturally found in skin—this daily serum binds to water and locks in moisture to visibly smooth and soften the face and neck. The fast-absorbing, non-comedogenic formula won’t clog pores and layers beautifully under makeup or moisturizer. Infused with the signature clean Hydro Boost fragrance, it provides instant, refreshing hydration while helping to strengthen the skin’s natural moisture barrier. For best results, apply evenly to face and neck after cleansing and before moisturizer. Pair with other Neutrogena Hydro Boost products for a complete hydrating skincare routine.
