Hyaluronic Acid 101: The Hydration Hero, Explained
Hyaluronic acid (HA) is one of the most talked-about ingredients in skincare, and for good reason. It's gentle, suits almost everyone, and delivers an immediate plumped, dewy look. But it's also one of the most misused ingredients we come across, so let's clear up what it really does and how to get the best from it.
What hyaluronic acid actually is
HA is a humectant, a molecule that attracts and holds water. It occurs naturally in your skin, where it helps keep tissue hydrated and cushioned. In skincare, it draws moisture into the upper layers of the skin, which softens the look of fine lines and gives that smooth, bouncy finish. It isn't an exfoliant or an active that changes the skin over time; think of it as deep, comfortable hydration.
The quick version
- Best for: every skin type, especially dry, dehydrated or tight-feeling skin.
- What it does: draws water into the skin for an instantly plumper, smoother look.
- How to use: apply to slightly damp skin, then seal with a moisturiser.
- The catch: in a dry climate, always lock it in, or it can draw moisture the wrong way.
How to use it properly
This is where most routines go wrong. Because HA pulls in water, it works best applied to slightly damp skin and then sealed with a moisturiser on top. Applied to bone-dry skin in a dry environment with nothing over it, it can actually draw moisture from deeper layers. The fix is simple: mist or apply to freshly cleansed, still-damp skin, then follow with a cream.

Frequently asked questions
Can oily skin use hyaluronic acid?
Absolutely. HA is lightweight and oil-free, so it hydrates without heaviness, useful even for oily skin that feels dehydrated.
Can I use it with other actives?
Yes. HA layers happily with vitamin C, retinoids and exfoliating acids, and can even make them feel more comfortable on the skin.
Morning or night?
Either, or both. A common approach is HA under sunscreen in the morning and under a richer cream at night.
