Hyaluronic acid serum: what it does and how to use it

Hyaluronic acid has grown into one of the best-known ingredients in modern skincare — and not without reason. A hyaluronic acid serum is a lightweight, fast-absorbing way to hydrate your skin intensely. But what exactly does it do, and how do you get the most out of it? In this guide, we explain it calmly.

What is hyaluronic acid?

Hyaluronic acid (sometimes shortened to HA or listed as sodium hyaluronate on the INCI list) is a substance that occurs naturally in the skin. What makes it special is its ability to hold a great deal of moisture. In a serum, hyaluronic acid attracts and holds moisture, for fresh, supple and comfortable-feeling skin.

What does a hyaluronic acid serum do?

A hyaluronic acid serum is first and foremost a hydration booster. It leaves the skin feeling plumper and more supple and gives a fresh, revived appearance. Because the texture is light, it absorbs quickly and doesn't feel heavy or greasy — ideal as an in-between step before your moisturising cream.

Many formulas combine hyaluronic acid with other caring ingredients. Our BioLift exosome hyaluronic serum by LUUV, for example, combines hyaluronic acid with plant-based exosomes and peptides, for cared-for, smoother-feeling skin.

Which skin is it suited to?

The lovely thing about a hyaluronic acid serum is that it suits almost every skin type — from dry to combination, and sensitive skin too. Dry skin in particular benefits from the extra hydration, while oilier skin appreciates the light, non-greasy texture.

How do you use a hyaluronic acid serum in your routine?

The order is simple. Work from light to rich:

• Cleanse — start with clean skin. A mild toner such as our facial cleansing toner can be a nice in-between step here.
• Serum — apply a few drops of hyaluronic acid serum to slightly damp skin and massage in gently.
• Moisturise — finish with a day cream or face oil to hold the moisture in.

A small tip: hyaluronic acid works most pleasantly on slightly damp skin, so that there is moisture to hold. Afterwards, always apply a cream or oil to seal everything in nicely.

What to look out for when choosing a serum?

• Ingredient list — check that hyaluronic acid (sodium hyaluronate) sits high enough on the list.
• Complementary ingredients — peptides, aloe vera or plant extracts can round out the care.
• Certification — a label such as COSMOS Organic shows that the serum meets strict natural standards.
• Fragrance-free — for sensitive skin, a fragrance-free formula is often more comfortable.

In short

A hyaluronic acid serum is one of the easiest ways to give your skin a hydration boost. Light, fast-absorbing and suitable for almost every skin type. Apply it to damp skin, seal with a cream, and your routine is complete.
