These Hyaluronic Acid Serums Will Give Your Skin an Instant Refresh

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 for a reason.

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 Dr. Sonia Batra, a dermatologist and co-host of The Doctors. Plus, like a good anti-aging cream or face serum, the major benefit is that it can be used daily to help turn back the clock. “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 plumps and smooths the appearance of fine lines,” Batra explains. Even better: There's practically no side effects and it plays nicely with other ingredients—which is exactly why you'll find this tried-and-true staple in tons of serums. (It's also pregnancy safe!)

So, which hyaluronic acid serum is best? While you might be tempted to buy a product with the highest concentration of hyaluronic acid, dermatologists actually recommend that you use a serum with just one percent hyaluronic acid, as higher levels can cause skin irritation. Additionally, you may want to look for one that's formulated with skincare stars like vitamin C and niacinamide, but without alcohol, sulphates, parabens, and other irritating ingredients.
