Our Favourite Hyaluronic Acid Serum of 2023

If you are always dreaming about plump, smooth and firm skin. Then it’s time to add Hyaluronic Acid into your skincare routine. Don’t be scared of the word ‘acid’, hyaluronic acid naturally occurs in your skin, joints, eyes and connective tissue. Together with the water, they create a fluid between the collagen and elastin fibres in the dermis. The amazing benefit of Hyaluronic Acid is that it helps to bind moisture to the skin. This means it will grab moisture from other products or the air around us and lock it into our skin. All this extra moisture in the skin subsequently reduces fine lines and wrinkles and boosts firmness as it plumps the skin.

The different benefits of using Hyaluronic acid are :

  • Anti-ageing
  • Moisturizing
  • Wound healing
  • Anti-wrinkle
  • Increases skin elasticity
  • Can treat eczema
  • Can treat redness

The correct way to use Hyaluronic Acid in your skincare routine:

  • Cleanser
  • Hyaluronic acid serum
  • Moisturiser
  • Sunscreen

What do we know about hyaluronic acid?

When browsing serums, you'll see there are more pure forms of HA, as well as options containing other key ingredients like vitamin C, vitamin B5, and niacinamide. 

To find out which ones work the best, we put some of today's top-rated hyaluronic acid serums to the test. 

Our testers used these products for weeks at a time, rating how well each improved their skin's hydration, plumpness, and overall glow. 

We combined these results with our own research and expert recommendations from dermatologists to compile a list covering every budget and skin concern.

Different acid concentrations

Some products feature the acid — or its salt form, sodium hyaluronate — as the star ingredient. They include a higher acid concentration because their main aim is to provide hydration and pro-aging support.

Others include a smaller amount that acts as a humectant to help with a different purpose, from treating acne breakouts to evening skin tone.

Different molecular weights

You may also notice various molecular weights on serum and cream labels.

“Hyaluronic acid comes in different sizes,” explains board certified dermatologist Rina Allawh, MD, who practices in Philadelphia.

“Each molecule is assigned a molecular weight, which inversely relates to how deep the molecule can penetrate the skin,” Allawh says. The lower the molecular weight, the deeper the molecules can go.

“A high molecular weight hyaluronic acid is more likely to create a film on the skin surface rather than penetrate deeper into the skin,” Allawh adds.

In other words, its effect may not last as long as that of a lower molecular weight acid. And, as Thomas points out, “substances with larger molecules often have trouble showing results.”

A small-scale studyTrusted Source, published in 2011, backs this up. After testing numerous hyaluronic acid weights, researchers found low molecular weight formulations were “associated with significant reduction of wrinkle depth, which may be due to better penetration abilities.”

How often should you apply a hyaluronic acid serum?

It’s always best to follow specific product instructions and to start off slowly.

Generally, though, you can safely use hyaluronic acid both morning and night.

Whether it’s a tried-and-true skin care regimen, how often you wash your hair, or the cosmetics you’re curious about, beauty is personal.

That’s why we rely on a diverse group of writers, educators, and other experts to share their tips on everything from the way product application varies to the best sheet mask for your individual needs.
