I love all skincare ingredients, but above all, I love hyaluronic acid. If you ask me, this superstar ingredient deserves to be at the top of everyone’s shelves—it’s genuinely one of the best skincare ingredients for dry, flaky skin. I talked with top derms to get the lowdown on this powerhouse hydrating ingredient and learn why it deserves a place in your routine.
“It is a substance that your body naturally produces to keep your joints and skin lubricated, hydrated, and flexible,” says Michael Jacobs, M.D., medical technology director at Cortina and clinical associate professor of dermatology at Weill Cornell Medical College. “Hyaluronicacid binds to water molecules already present in your skin to lock in the hydration.”
Since it binds to water and helps skin retain moisture, it’s classified as a humectant, according to Reid Maclellan, M.D., M.M.Sc., founder and CEO of Cortina, adjunct faculty at Harvard Medical School and director of Proactive Dermatology Group. Maclellan notes that your body stops producing as much hyaluronic acid as you age.
Everyone can use hyaluronic acid. It’s one of those rare universal skincare ingredients. “No matter your skin type or age, hyaluronic acid can lead to healthier and dewier skin,” says Maclellan. “It helps keep our skin plump, voluminous, hydrated, and healthy-looking.” If you have dry skin, however, hyaluronic acid will be especially beneficial.
Hyaluronic acid is also an incredibly effective anti-aging ingredient, according to Jacobs. “Skin aging is associated with the loss of elasticity and moisture, which are two things that hyaluronicacid can combat,” he says. “[Its] plumping properties can decrease the appearance of wrinkles and lines and tighten and brighten the skin.” Hyaluronic acid is found in injectables, serums, creams, and even supplements.
Hyaluronic acid has gotten a bad rap over the years, with some people saying that it can dry out your skin more. The trick is using hyaluronic acid correctly. Maclellan advises that you need to make sure your skin is already damp if you’re using hyaluronic acid in serum form so that it has water to retain. He also recommends doing a patch test and reading the ingredients to ensure there are no other potential irritants added.
