Hyaluronic acid is one of the easiest hydrating ingredients to add to a routine. It is gentle, it suits most skin types, and it does not need a long adjustment period. The hard part is choosing between dozens of bottles that all promise the same plump, dewy result.
We compared five popular hyaluronic acid serums on formula, texture, price and who they suit best. If you are new to the ingredient, our hyaluronic acid guide explains how it works in more detail.
What Makes a Good Hyaluronic Acid Serum
What It Can and Cannot Do
Hyaluronic acid is a humectant, which means it draws water into the outer layers of the skin and helps it hold that water. It can make skin look and feel smoother and bouncier. It is not an anti-ageing treatment on its own, and it will not replace a moisturiser. Think of it as a hydration layer that a cream then seals in.
Ingredients to Look For
Look for serums that pair hyaluronic acid with supportive ingredients such as vitamin B5 (panthenol), glycerin, ceramides or niacinamide. Some formulas use several molecular weights of hyaluronic acid, which is meant to hydrate at different depths of the skin surface. Smaller molecules may sit deeper while larger ones form a light film on top.
Things to Be Careful With
Apply hyaluronic acid to damp skin and follow with a moisturiser. In very dry air, a humectant used on bone-dry skin without a seal on top can feel tight. Fragrance and heavy essential oils are common in hydrating serums, so check the label if your skin is reactive.

1. Best Budget Pick: The Ordinary Hyaluronic Acid 2% + B5
This is the serum most people try first, and for good reason. It combines hyaluronic acid at several molecular weights with vitamin B5 in a water-based formula at a very low price. The texture is slightly tacky on its own, which is normal, and it settles once you apply moisturiser over the top.
Best for: beginners and anyone who wants proven hydration without spending much
2. Best for Dry Skin: CeraVe Hydrating Hyaluronic Acid Serum
CeraVe pairs hyaluronic acid with ceramides and vitamin B5, so it hydrates and supports the skin barrier in the same step. The formula is fragrance-free and has a gentle, slightly creamy gel feel. It is a sensible choice if your skin feels tight or flaky.
Best for: dry or barrier-compromised skin
3. Best Lightweight Booster: Vichy Minéral 89 Hyaluronic Acid Booster
This daily booster combines hyaluronic acid with mineralising thermal water from the Vichy volcanic region. It has a light, fresh texture that layers well under sunscreen and makeup, which makes it easy to use every morning.
Best for: combination skin and anyone who dislikes heavy serums
4. Best Multi-Weight Formula: Naturium Quadruple HA Serum 5%
Naturium uses four forms of hyaluronic acid in one bottle, which suits anyone who likes the idea of hydration at several levels. It has a smooth, slightly cushiony feel and a modest price for the amount of hyaluronic acid on the label.
Best for: people who want a fuller, bouncier hydration step
5. Best Simple Everyday Option: Good Molecules Hyaluronic Acid Serum
A short, no-fuss ingredient list and a very approachable price make this a good daily serum for people who like their routine minimal. It is light, absorbs quickly and pairs easily with other actives.
Best for: minimalists and budget-conscious shoppers
How We Chose These Serums
We looked at the type and number of hyaluronic acid weights, supporting hydrators such as B5 and ceramides, fragrance content, texture, price and how easily each serum fits into a routine. We prioritised products with clear ingredient lists and sensible claims, and we avoided anything that relies on heavy fragrance or irritating extras.

How to Use a Hyaluronic Acid Serum
- Cleanse your face and leave it slightly damp.
- Apply two to three drops of serum and press it in.
- Follow straight away with a moisturiser, such as one from our best peptide moisturizers, to seal in the water.
- In the morning, finish with sunscreen. Our SPF guide covers how much to use.
Hyaluronic Acid vs Other Hydrators
Hyaluronic acid is a humectant that attracts water, while ceramides are barrier lipids that help keep it in. Niacinamide supports the barrier and evens tone, and peptides signal the skin to build structure. They work well together, so you do not need to choose. Hyaluronic acid with ceramides is a good place to start, and you can read more in our ceramides guide and niacinamide guide.
Hyaluronic Acid Serum FAQ
Can I use hyaluronic acid every day?
Yes. It is gentle enough for twice-daily use for most skin types, as long as you follow with a moisturiser.
Does hyaluronic acid work on oily skin?
Yes. Oily skin can still be dehydrated, and a light hyaluronic acid serum adds water without adding oil.
Can I use it with vitamin C or retinol?
Generally yes. It layers well with most actives and can make them feel more comfortable. Our guide on peptides with vitamin C covers combinations.
Why does my face feel sticky?
Too much product is the usual cause. Use fewer drops and apply on damp skin.
Product formulas change from time to time. Always check the current ingredient list before buying.
