In 2017, there's an infinite list of skincare actives and ingredients at your disposal. But we love a classic—and there's a million different reasons why hyaluronic acid should be your hero this summer.

A little background: Hyaluronic acid isn't new. In fact, it exists in your skin naturally. The protein acts as a sponge for moisture and can hold up to 1,000 times its weight in water. While this is important during the colder months, it's all the more enticing in summer when the air is more humid and you don't want to slather on a heavy-duty moisturizer.

According to Dr. Ulysses Scarpidis, director of plastic surgery at Scarpidis Aesthetics and New York Plastic Surgery, hyaluronic acid is not an occlusive barrier and thus "it continues to allow your skin to breathe and doesn't add oil to the surface, making it a great moisturizer for oily or acne prone skin."

While many acne treatments work by decreasing oil production in the skin, which can cause significantly dry and flaky skin, hyaluronic acid can help maintain hydration and reduce irritation without contributing to flare ups.

Another reason it's great for summer: If you experience breakouts from excessive sweat, hyaluronic acid will have you covered there too thanks to its antibacterial properties. "Hyaluronic acids are lengthy, linear proteins devoid of branching molecules that can inhibit bacterial adhesions," explains Dr. Scarpidis. As such, it serves as a complement to antibiotics in decreasing bacterial counts on the skin surface.

Easily layered with SPF, hyaluronic acid draws from the air to keep your skin plumped, fresh, and glowing. In other words, dehydrated and lackluster skin doesn't stand a chance against it. So before you invest in a new seasonal moisturizer, make sure it's at the top of that ingredient list.
