Dryness, flaking, foundation settling into fine lines: You might be thinking your skin needs an entire overhaul now that winter’s fully arrived, but it’s way, way simpler than that. In fact, your skin needs but one ingredient to look plumper on the fly—and it’s pretty affordable: hyaluronic acid.
“Hyaluronic acid is a potent humectant so by pulling in hydration you can get a plumping effect,” dermatologist Heidi Waldorf tells us. “That way the skin looks better temporarily,” The tiny molecule, which appears in everything from serums to moisturizers, can hold up 1000-times its weight in water, leaving your complexion looking bouncy and well-hydrated almost instantly.
“Plus, skin that’s well-moisturized tends to not only look better but it feels better and functions better—cells turnover better and it is more flexible and less likely to be irritated by the environment or irritants,” explains Dr. Waldorf.
Now that we’ve broken it down for you, it’s time to get shopping: Ahead, nine products packed with hyaluronic acid that’ll transform your skin this winter.
