The Hyaluronic Acid 3 Serum is a deeply hydrating formula that delivers instant moisture and long-lasting plumpness to the skin. With three molecular weights of hyaluronic acid, it penetrates multiple layers of the skin to hydrate from within and lock in moisture on the surface.
The texture is lightweight, non-sticky, and absorbs quickly, making it perfect for layering under moisturizers and makeup. After regular use, my skin feels smoother, softer, and visibly more supple. It helps reduce the appearance of fine lines caused by dryness and gives the skin a fresh, dewy glow. Suits all skin types — even oily or sensitive — without clogging pores or causing irritation. It’s an ideal everyday serum for boosting hydration and supporting overall skin health.
