Like other face serums we’ve tested, our chemists evaluated hyaluronic acid formulas based on laboratory and consumer tests. We use technical instruments in our Beauty Lab to measure skin changes — such as moisturization, elasticity, wrinkles and pores — after product use. To see how it works on different skin types in real life, our consumer testers try products out and give feedback on their ease of use. Other top-tested picks above, like Seal holders, underwent rigorous evaluation by our scientists who verified product claims. We also included everyday favorites from our GH staffers who struggle with dry or sensitive skin and use hyaluronic acid regularly.

✔️Keep an eye on concentration: Most hyaluronic acid formulas offer a concentration of 2% or less. “Using concentrations greater than 2% can negatively impact the skin, pulling water out of the skin [and] creating dryness,” Dr. Mack says.

✔️Do double-duty: Pairing well with other skincare ingredients, hyaluronic acid can help reduce side effects such as irritation from ingredients like vitamin C and retinol, according to Dr. Mack.

✔️Cater to your skin type: If you have a drier skin type, Dr. Mack recommends using HA serums twice a day, prior to applying moisturizer — dry skin can benefit from that added boost of hydration. For normal to combination skin types, apply nightly following a retinoid to help soothe any sensitivity.

Hyaluronic acid can also have anti-aging effects, thanks to its skin-plumping properties. “It acts like a sponge that absorbs water, adding volume to skin,” Dr. Gohara says. Serums, which are lighter weight in texture than face moisturizers like lotions or creams, deliver the hydrating benefits of hyaluronic acid without heaviness and can be layered underneath other leave-on skincare products morning, evening or both.

We tapped Senior Chemist Sabina Wizemann for our Beauty Lab’s top-tested picks, included above. For almost a decade at GH, she’s researched, tested and evaluated thousands of products, while also verifying product claims based on her extensive knowledge of skincare ingredients. Collaborating closely with our Institute experts, Beauty Director April Franzino oversees all beauty content at GH. She spearheads our Beauty Awards and regularly writes science-backed roundups. Having dry skin herself, she wrote this original roundup of hyaluronic acid serums. Our Associate Product & Reviews Editor Jacqueline Saguin updated this story with our latest batch of expert-tested picks. She also interviewed dermatologists to answer the most searched questions about hyaluronic acid. Jacqueline also struggles with dry, sensitive skin and considers HA serums a crucial part of her skincare routine.
