Hyalu-Huh? Get the Scoop on Hyaluronic Acid and Why You’ll Want to Use it as You Age

hyaluronic acid

We spoke to a dermatologist about when and how to use this impactful ingredient.

You’ve probably seen the term hyaluronic acid plastered across various products in the skincare aisle. (Or maybe you’ve seen Eva Longoria touting it in that L’Oreal Paris commercial, or noticed that Gwyneth Paltrow swears by a lip balm that includes the ingredient.) But do you know what it is? And is it safe to use?

What is hyaluronic acid?

When you hear the word “acid,” you might imagine an ingredient that could burn off the top layer of your epidermis. But that’s not the case here: Hyaluronic acid is something our bodies naturally produce, and is very mild on the skin. “Hyaluronic acid is a natural sugar, and its primary function is to absorb water,” says Angela J. Lamb, MD, a New York-based dermatologist. But as we age, our production of hyaluronic acid naturally decreases. “It’s naturally produced by our body but there’s less production as we mature, which is why older skin tends to be dryer,” says Dr. Lamb.

What does hyaluronic acid do?

Many moisturizers and serums contain hyaluronic acid because this hardworking ingredient plumps up your skin with much-needed hydration. “It’s used as an ingredient in many moisturizers, and it’s the primary ingredient in most cosmetic fillers,” says Dr. Lamb.

It’s also safe to use on all skin types and at all ages, according to Dr. Lamb, “because it moisturizes without being too heavy.” 

The best part is that after just a few days of using a hyaluronic acid-based serum or moisturizer, you’ll start to see an improvement. “The main way it functions is by absorbing moisture, so you should see results quickly,” says Lamb. 

So if your skin is already feeling as dry as the Sahara, it might be time to treat yourself to the extra moisture that hyaluronic acid can provide. Below, we’re sharing Dr. Lamb’s go-to serum, plus a few other hyaluronic acid products we love here at Katie Couric Media.
