Best hyaluronic acid serum 2023: The top serums to hydrate your skin and smooth out wrinkles

Level up your skincare game with the best hyaluronic acid serums for glowing, hydrated skin

You may have heard a lot in recent years about hyaluronic acid (HA), the wonder ingredient that has found its way into seemingly everything from face creams and foundations to shampoos and eyelash treatments. A brilliant hydrator, hyaluronic acid helps to plump up and retain moisture in the skin, smoothing away fine lines and wrinkles and giving skin a younger, fresher feel.

A facial serum is the most potent way to give your skin a concentrated burst of any skincare ingredient, and a serum primarily containing hyaluronic acid is an efficient way to infuse the skin with this plumping and hydrating wonder-stuff. If your goal is softer, firmer, fresher skin, adding a layer of HA serum to your skincare routine can really make a difference to your skin’s hydration levels and overall texture.

Below we talk about how an HA serum can help your skin look and feel its best, and we’ve then tested HA serums at a range of price points to help you pick the best for you.

How to choose the best hyaluronic acid serum for you

What is hyaluronic acid?

Hyaluronic acid is a lubricant produced naturally by the body. While it is (as the name implies) an acid, it’s not a strong exfoliant like salicylic acid; rather it’s a gentle fluid humectant that acts like a sponge to soak up and retain moisture in the skin. Each molecule of hyaluronic acid is able to absorb and hold many times its own volume in water, which produces the plumping effect we see naturally in young skin, which makes plenty of its own hyaluronic acid.

As skin ages, we produce less of this lubricating and hydrating natural acid, which is one reason skin tends to become dryer and dehydrated as it gets older, leading to fine lines and wrinkles. Replacing the body’s own supply using products containing hyaluronic acid is a good way to put back some of that hydrating and plumping power. Skin will look and feel softer and fresher as soon as you use a hyaluronic acid product; and over time, skincare products containing hyaluronic acid will help the skin to maintain its own supply of moisture, reducing the appearance of fine lines and wrinkles.

Hyaluronic acid also has healing and anti-inflammatory properties, making it an excellent product to use to heal and hydrate irritated or sensitive skin. A great product to help dry skin retain moisture, hyaluronic acid is a good lightweight and non-greasy ingredient to help balance oilier skins.

How should I apply my hyaluronic acid serum?

An HA serum is best used after cleansing but before moisturising, to allow the product to sink into the skin and get all the hydrating goodies where they need to be. Apply a pump or two of serum to the face and neck with light fingertip strokes, and follow with an optional spritz of plain water and your favourite moisturiser.

It’s up to you if you use your HA serum as part of your morning or your night-time routine; if applying in the morning, give the product time to sink in before applying moisturiser and makeup, as serum formulations can be quite runny and may cause your makeup to slide off if not properly absorbed.

Unlike some products, such as vitamin C or retinol, hyaluronic acid is gentle enough to be used daily; there’s no need to build up usage slowly over time. Once you’ve picked your preferred serum, you can apply it straight away as often as you’d like.

What should I use afterwards?

Hyaluronic acid serum is great at trapping moisture in the skin, but serum formulations aren’t so good at providing an occlusive layer (the final skincare layer that traps in all the softening and moisturising ingredients). You’ll probably find that a serum on its own leaves skin a little dry and prickly, so you’ll want to finish with a nourishing moisturiser to trap all that hydrating goodness inside the skin and leave your face feeling smooth and comfortable. Simply apply your favourite face cream after the HA serum to lock in moisture at bedtime, or before you start your morning makeup routine.

How we test hyaluronic acid serums

At Expert Reviews, we know that hands-on testing delivers the most complete information about a product. When it comes to testing hyaluronic acid serums, we personally assess every product that features in the roundup below, following the directions on the packaging.

We start by noting all of the active ingredients used in the formula; all the serums below list hyaluronic acid as an active ingredient. Using each of the products as directed for one week, we pay particular attention to the benefits it brings in terms of softening and plumping, and its impact on fine lines and wrinkles. We consider how comfortable it feels on the skin immediately after use and throughout the day, while also considering its smell, as well as any issues with greasiness or stickiness on the skin.

The best hyaluronic acid serums to buy

1. The Ordinary Hyaluronic Acid 2% + B5: Best budget hyaluronic acid serum

Price: £5.90 | Buy from Cult Beauty

Iconic budget brand The Ordinary is known for its combination of high-quality ingredients and minimalist packaging to make quality skincare affordable for all. This simple yet powerful combination of hyaluronic acid and vitamin B5 works deep in the skin; three different sizes of hyaluronic acid molecule are able to penetrate different levels of the skin to provide plumping hydration from the inside out. The result is soft, dewy skin that feels fresher, and shows fewer fine lines.

The Ordinary’s serum formula is gentle enough for all skin types, vegan and oil-free, making it particularly suitable for oilier skins that don’t get on well with added oils. If your skin is dryer, we’d definitely recommend following the serum with a nourishing moisturiser.

2. Boots Ingredients Hyaluronic Acid Serum: Best on the high street

Price: £5 | Buy from Boots

Single-ingredient products have become hugely popular in recent years, in no small part due to the popularity of brands like The Ordinary. Boots recently launched its own range of simple products with single or minimal ingredients, and this plant-derived hyaluronic acid serum is a great no-frills hydrating and brightening product. The lightweight serum feels silky and sinks into the skin easily. The Ingredients hyaluronic acid range also includes a lightweight moisturiser and sleep mask, which feel fresh and hydrating on oily and combination skin; dry skins may prefer to follow with a richer moisturiser.

Glossier’s non-sticky serum is quickly absorbed into the skin, making it ideal for morning application before makeup; it’s also a great hydrating serum for winter weather. The £24 price tag is higher than some of our budget options, but this is a quality product that will freshen and plump up all skin types; and the pretty pastel bottle will look nice on your nightstand, too.

One of the most popular hyaluronic acid serums on the market – L’Oreal reports one bottle sold every minute in the US – Revitalift is an intensely hydrating serum with a 1.5% concentration of hyaluronic acid in two molecular weights, to penetrate the deeper skin layers as well as hydrating the surface. The serum feels light and non-sticky and absorbs well; skin feels immediately fresher, calmer and more hydrated. With longer-term use, fine lines and wrinkles appear reduced and skin is better able to hold moisture. A good serum for all skin types, this is particularly suitable for dryer and more mature skins. Combine with the hyaluronic acid tissue sheet mask in the same range for a weekly plumping treat.

5. Drunk Elephant B-Hydra Intensive Hydration Serum: Best for intensive hydration

Price: £40 | Buy from Cult Beauty

Cold weather, central heating, air conditioning and other environmental factors can cause skin to become dry and dehydrated. If tight, dry or flaky skin is your major skin concern then this super-hydrating blend of hyaluronic acid and natural fruit extracts may be just what you need. The lightwight gel – combining coconut, watermelon and apple extracts with vitamin B5 and gentle sodium hyaluronate – sinks right into the skin, providing instant moisture, and smells wonderful too.

Almost as important is what the serum doesn’t contain: there’s no synthetic fragrance, colour, alcohol or silicone to irritate or further dry out already dry skin. A couple of pumps of B-Hydra each day will help skin feel refreshed and comfortable as well as looking moist and dewy.
