Neutrogena Hydro Boost Hydrating Hyaluronic Acid Face & Neck Serum is a lightweight, fast-absorbing daily moisturizer formulated with purified hyaluronic acid, a naturally occurring substance known for its ability to attract and retain moisture in the skin. This serum is designed to provide lasting hydration to both the face and neck area, helping to maintain a smooth and supple texture without leaving a greasy residue. The oil-free and non-comedogenic formula ensures that it will not clog pores, making it suitable for a wide range of skin types, including oily, combination, and sensitive skin. The absence of heavy oils and the quick-absorbing texture allow it to be used alone or layered under sunscreen, makeup, or other skincare products without interfering with their performance. Regular use of this serum supports the skin’s natural moisture barrier, helping to improve the appearance of dryness and fine lines over time. By delivering a concentrated dose of hydration directly to the skin, it helps maintain a balanced level of moisture throughout the day. The formula is free from fragrance and dyes, reducing the risk of irritation for those with reactive skin. It comes in a 1 fl. oz bottle with a pump dispenser for controlled and hygienic application. This product is intended for daily use as part of a simple skincare routine, applied to clean skin morning and evening before heavier moisturizers. It is not recommended for use on compromised or broken skin. As with any personal care item, a patch test is advisable prior to full application, especially for individuals with known sensitivities.
