Neutrogena Hydro Boost Ultra Moisturizing Serum is much more than a simple skin care product. It's your ally for visibly softer, more supple and radiant skin. Enriched with Natural Moisturizing Factors (NMF), including hyaluronic acid, amino acids and electrolytes, this lightweight, fast-absorbing serum provides intense, long-lasting hydration. Thanks to its unique formula enriched with hyaluronic acid, this serum provides instant hydration 8 times more* than other similar products. You will immediately feel the benefits of intensely hydrated skin, ready to face everyday challenges. Hyaluronic acid is a true ally for radiant and hydrated skin. Naturally present in our bodies, this key ingredient has the remarkable ability to retain moisture, making it a powerful moisturizer for the skin. When applied topically, hyaluronic acid acts like a sponge, absorbing water to deeply hydrate the skin and restore its natural elasticity. It also helps to smooth fine lines and wrinkles, giving the skin a younger, fuller appearance. Thanks to its moisturizing and plumping properties, hyaluronic acid is essential for anyone looking for soft, supple and radiant skin. In addition to its moisturizing action, this serum works in depth to reinforce the skin barrier, helping your skin to better protect itself from external aggressors, such as pollution and UV rays. A healthy skin barrier is essential for maintaining radiant, resilient skin. Thanks to its light, non-greasy texture, this serum quickly penetrates the skin, leaving it supple and luminous. No more feeling of tightness and discomfort! Enjoy visibly brighter skin from the first application. Designed to adapt to even the most sensitive skin, this serum is fragrance-free, reducing the risk of irritation or allergic reaction. You can use it with confidence, day after day, for continuous hydration and a radiant complexion.
