Ask A Derm: Why Does Everyone Want Me to Use Skincare with Hyaluronic Acid in It?
I know it's important, but I'm not sure where to start!

Everyone knows you should take your makeup off before bed and slather on sunscreen, but hyaluronic acid? It’s one of the most consistently recommended ingredients by dermatologists, but very few people actually know what it is or why they’re supposed to be incorporating it into their skincare routines. In fact, in a recent goodhousekeeping.com poll, only four in 10 readers said they used a product containing hyaluronic acid in it—and only 35% of readers knew what it did for their skin.
To help you better understand why you should be including HA into your routine, we talked with Dr. Ellen Marmur, a board-certified dermatologist and founder of Marmur Medical in New York City. As she explains, hyaluronic acid is a substance naturally found in the body—it’s a sugar molecule that acts like a sponge to soak up moisture in the air and draw it into the skin.
Hyaluronic acid is able to hold up to 1,000 times its weight in water.
Unfortunately, over time, your body starts to lose some of its naturally-occurring HA, but (luckily for our skin) there are plenty of HA-packed products on the market that fill in the gaps—and because of the ingredient’s versatility, it works well in a wide variety of formulations, from serums to makeup.
HA is able to hold up to 1,000 times its weight in water, which also gives it the ability to add plumpness to the skin and minimize the appearance of fine lines and wrinkles. And, despite the misleading “acid” in its name, HA does not have any sort of exfoliating or irritating properties—it’s simply a gentle hydrator that works for all skin types.
“As a dermatologist, I love that hyaluronic acid is a lightweight, yet powerful humectant,” says Dr. Marmur. “It’s one of the most logical and healthy ingredients for providing your skin with humidity and moisture.”
Below, Dr. Marmur answers questions about the best way to add HA to your beauty routine, plus lists her top HA-related serums, moisturizers, eye creams, and makeup. All of her product picks are available to shop online at Dermstore, the retail destination famous for its derm-approved selection of standout beauty brands and essential skincare info, from ingredient explainers to expert skin concern solves.
