Plump, dewy skin owes much to hydration, and hyaluronic acid skincare is one of the most beloved ways to keep moisture right where you want it. This humectant draws water into the skin's surface, appearing in lightweight serums, gel creams, masks, eye formulas, and lip balms. Layer it on damp skin and seal with a moisturizer to enjoy a supple, bouncy complexion that looks smoother, fresher, and radiantly hydrated from morning to night.
