In plain English: Skin feeling tight after a shave, or in an air-conditioned office all day? Hyaluronic acid pulls water into your skin so it feels comfortable again. It’s gentle enough for anyone.
Hyaluronic acid (HA) is a sugar molecule found naturally in skin, where it holds water and keeps tissue plump. In skincare, it acts as a humectant, drawing water into the outer layer of the skin.
What it does
- Hydrates instantly, making skin look plumper and smoother.
- Reduces the look of fine dehydration lines.
- Supports comfort when using drying actives like retinol or acne treatments.
How to use it
Apply a few drops to damp skin after cleansing, then seal with moisturiser. In very dry air, the moisturiser step matters: without it, HA can draw water from deeper skin and let it evaporate. See Hyaluronic Acid in Humid vs Dry Climates.
Who should use it
Anyone whose skin feels tight, especially in winter, in air-conditioned offices, or while using retinol.

Frequently asked questions
Is hyaluronic acid an exfoliant?
No. Despite the word 'acid', it does not exfoliate. It is a hydrating sugar molecule your skin already makes.
Can oily skin use hyaluronic acid?
Yes. It adds water, not oil, and is one of the best ways to hydrate oily skin without heaviness.
