Neutrogena Hydro Boost Serum 10% Niacinamide 30ml is designed for those seeking to hydrate their skin and improve its texture and appearance, especially when it appears dull, uneven, or with visible pores. Its formula combines 10% pure niacinamide, a form of vitamin B3, with hyaluronic acid, providing daily care that simultaneously hydrates and improves the overall appearance of the skin. Niacinamide is a widely used ingredient in facial care due to its ability to contribute to a more even complexion and smoother skin texture. In this serum, it is present at a concentration of 10%. Hyaluronic acid helps retain water, contributing to increased skin hydration. The formula also contains glycerin and acetyl glucosamine, ingredients associated with skin hydration and texture care. The brand indicates that the serum hydrates from the first use and helps to visibly refine the appearance of pores. In self-assessment tests conducted by the manufacturer, improvements in skin smoothness, texture, evenness, luminosity, and flexibility were also observed after continued use. These results correspond to the participants' evaluation and do not constitute a guarantee of individual results. The texture is light, absorbs quickly, and is non-sticky, and can be used before moisturizer and under makeup. It is fragrance-free and suitable for all skin types.
