20 Best Hyaluronic Acid Serums That Work Magic on Your Skin

Just like retinol and broad-spectrum sunscreen, hyaluronic acid is one of the few ingredients that’s recommended by most (if not all) dermatologists. The molecule—often listed as sodium hyaluronate, hyaluronan, or hydrolyzed hyaluronic acid on the ingredient list—is popular among skincare experts because when applied topically, this humectant, which is naturally found in the body, acts like a tiny sponge that pulls in water to quench and plump skin, says Sonia Batra, MD, a board-certified dermatologist.

“As we age, our skin loses moisture and becomes less firm and supple. Hyaluronic acid is an oil-free ingredient that works to replenish the skin’s moisture as well as plump and smooth the appearance of fine lines,” Batra explains. Even better: There are practically no side effects, it’s pregnancy-safe, and it plays nicely with other ingredients—which is exactly why you’ll find hyaluronic acid in tons of serums.
