Hyaluronic Acid: How to Make It Actually Hydrate

October 27, 20262 min read

Hyaluronic acid is in almost every serum, yet plenty of people swear it makes their skin feel drier. The difference is all in how you use it.

What is hyaluronic acid?

Hyaluronic acid is a sugar molecule your skin makes naturally. It holds onto water, drawing moisture into the top layers of skin. On labels it often appears as Sodium Hyaluronate, and many Korean formulas blend several sizes (low, medium and high molecular weight) to hydrate at different depths. Glycerin and betaine work in a similar way and often appear alongside it.

What it does for your skin

Draws in moisture. It pulls water into skin for an instant plumper, bouncier feel.
Smooths the look of fine dry lines. Well-hydrated skin looks smoother and fresher.
Lightweight. It hydrates without heaviness, so it suits every skin type.

Who it suits

Everyone, especially dehydrated skin that feels tight but still gets oily. Great in Australian summers when aircon dries skin out.

How to use it

Apply to damp skin, straight after cleansing or toner.
Seal it in with a moisturiser. Without that last step, water can evaporate and leave skin feeling drier.
Use morning and night.

When you'll notice it: You'll feel the plump, bouncy effect straight away. Skin looks smoother after a couple of weeks of daily use.

Good to know: One of the gentlest ingredients in skincare. Most skincare hyaluronic acid is made by fermentation, not from animals.

What to pair it with

Pair with ceramides or squalane to lock the water in. It works well with niacinamide, panthenol and almost everything else.

Myth vs fact

Myth: More molecular sizes always means better.
Fact: Multi-size blends are great, but the bigger win is applying to damp skin and sealing with a cream.

How to choose one

Look for Hyaluronic Acid, Sodium Hyaluronate or a 'multi-molecular' blend.
Use a serum or toner for layering, then a cream to seal it in.
In a humid summer a light gel may be enough. In dry winter air or all-day aircon, add a richer cream on top.

Where to find it

KIWIGLOW's Gold Kiwi serum carries eight types of hyaluronic acid, and SÉLEVÉ's bubble toner pairs it with panthenol. From the big names, Torriden's DIVE-IN line is built around 5D low-molecular hyaluronic acid.
