Hyaluronic acid holds up to 1,000× its weight in water — here's how to make it work for your skin instead of against it.
Hyaluronic acid (HA) is one of the most talked-about ingredients in skincare — and for good reason. It's a humectant, meaning it draws and binds water to the skin, leaving it plumper, smoother and more comfortable.
What it actually does
Your skin already contains HA, but levels fall with age and exposure. A topical serum tops it up at the surface, softening the look of fine lines that are really just dehydration.
How to use it
- Apply to damp skin, not dry — HA pulls in whatever water is available.
- Layer a moisturiser on top to seal that hydration in.
- Use morning and night; it suits every skin type, including oily and sensitive.
Pair it with a brightening HA serum as your second step, then lock it in with a moisturiser and SPF by day.
