This popular skin care ingredient might be the secret to softer, fuller lips

These picks will give your lips a major hydration boost.

Take a peek into any skin care lover's beauty cabinet and you're likely to find a slew of products that feature hyaluronic acid as the star ingredient. The hydrating powerhouse is a staple in many bestselling creams and serums and is beloved by dermatologists since it's a great moisturizer and has little to no side effects.

Surprisingly, the ingredient can be just as beneficial for your pout as it is for your skin. "Just like the rest of our skin, our lips are susceptible to moisture loss, as well as getting dry, cracked and irritated," Dr. Marisa Garshick, a board-certified dermatologist in New York City, told Shop TODAY. "What hyaluronic acid does, because it’s a humectant, is it draws moisture in." In short, this leaves your lips feeling softer, smoother and more hydrated.

On top of that, it can also have a subtle plumping effect. "Hyaluronic acid is one of the most common filler ingredients which we use for lips," Garshick said. "But topically, while it’s obviously not going to have the same effect that an injectable would, it does have great hydrating properties." As a result, after applying an HA-containing product, you may notice that your lips look naturally fuller and more voluminous.

Below, Garshick shared with us the hyaluronic acid lip products that she's tried and loved. Plus, we found a handful of other popular options that you can add to your beauty cabinet as well.

Hyaluronic lip balms

artnaturals Lip Balm Serum Trio

Why settle for one beneficial ingredient when you can have three? This trio of lip balms each feature a different serum as the star ingredient, including hyaluronic acid, retinol and vitamin C. For less than $7, you can begin your journey to hydrated, plump-looking lips.

Charlotte Tilbury Hyaluronic Happikiss Lipstick Balm

You can keep this formula in your purse to swipe on whenever your lips need a quick boost of moisture and color. Available in eight flattering shades like light pink or deep red, there’s a hue to match every makeup look.

Biossance Squalane+ Rose Vegan Lip Balm

This lip balm blends hyaluronic acid with other hydrating ingredients like ceramides and squalane to smooth and soften your pout. Even better, it contains wakame algae, which the brand says can help visibly improve the plumpness of your lips with repeated use.

Kosasport LipFuel Hyaluronic Acid Lip Balm

This is not your average lip balm. The LipFuel Hyaluronic Acid Balm from clean beauty brand Kosas is packed with nourishing ingredients like hyaluronic acid, konjac root and vitamin E, which visibly improves the appearance of your lips with every wear. The stick's design is meant to mimic the shape of your lips, so you can cover all the corners and crevices. Get it in a clear shade or try one of the lightly tinted hues.

Hyaluronic lip glosses

Maybelline New York Lifter Gloss

With over a dozen colors available from clear to shades of bronze and brass, you don't have to worry about sacrificing moisture for beauty with this lip gloss. Hyaluronic acid is a key component to its formula so you can have the glossy sheen you desire while still delivering much-needed hydration to your pout.

Colorescience Sunforgettable Lip Shine SPF 35

Garshick likes this Lip Shine, which not only contains hyaluronic acid for hydration but also provides necessary sun protection. Since hyaluronic acid draws moisture in, when looking for an HA-containing product, she said that you also want to make sure there are ingredients that will hold it in. She recommended looking for occlusives like shea butter or vitamin E — this formula contains the latter.

Neutrogena Hydro Boost Hydrating Lip Shine

The bold color of a lipstick, shine of a gloss and hydrating qualities of a balm all for less than $10? Yes, please! This do-it-all lip gloss provides up to 24 hours of moisture thanks to the addition of hyaluronic acid. Reviewers say that they appreciate how the gloss goes on smoothly without feeling sticky and provides an instant dose of hydration.

Ilia Balmy Gloss Tinted Lip Oil

Not only is this formula a celebrity favorite, but it’s also dermatologist-approved. It can be applied over your favorite lipstick shade or on its own to add color, moisture and shine to your lips. One Shop TODAY editor said that "it glides on smooth, giving my lips a more plump experience and a more cushioned feeling."

Other hyaluronic lip products

Paula's Choice Boost Hyaluronic Acid + Peptide Lip Booster

This lip boosting serum is made up of three major players in skin care: hyaluronic acid, peptides and squalane. It touts a plethora of benefits like improving fine lines and flaking, restoring suppleness, preventing moisture loss and aid in giving you smoother, softer lips.

PCA SKIN Hyaluronic Acid Lip Booster

Garshick said that this Lip Booster is a good pick for someone who is looking to get that plumping effect along with a boost in hydration. "It also contains peptides, which are thought to help stimulate collagen production so it may also be helpful for lip lines as well," she said.

Indeed Labs Hydraluron+ Volumising Lip Treatment

Garshick also recommended this treatment, which she called "very soothing." It features the hydrating ingredient along with fruit extracts to relieve dryness and boost lip radiance and softness.

First Aid Beauty Ultra Repair Lip Therapy

Free from alcohol, artificial colorants, artificial fragrance and other unwanted ingredients, this lip treatment is made with just the good stuff.
