The formula centers on hyaluronic acid (high molecular weight) to attract and hold moisture, plus Vitamin B3 to support the skin barrier and a natural moisturizing factor (NMF) booster that encourages the skin's own hydration mechanisms. Presented in a precision dropper bottle, the serum layers easily under moisturizers and makeup without leaving greasiness.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does the serum hydrate skin?\u003c\/h3\u003e\n\u003cp\u003eThe water‑gel texture is designed to sink in immediately and provide an intense, refreshingly cool sensation that boosts surface hydration right away.
