Hyaluronic Acid Serum

There's a reason The INKEY List Hyaluronic Acid Serum is the brand's best-selling face serum — by The INKEY List's own 2022 sales data, one is sold every 20 seconds worldwide. It's a fast-absorbing, non-tacky hydration shot that plumps skin, softens the look of fine lines and makes everything layered on top of it work a little harder.

What it actually does

• Hydrates at multiple depths. 2% multi-molecular hyaluronic acid pulls in water intensely and locks that moisture down.
• Plumps with peptides. Matrixyl 3000™ supports the skin's natural collagen production for a visibly plumper look.
• Strengthens the barrier. The brand's 4-week independent clinical study of 22 people, run under dermatological control, found it hydrates instantly and contributes to a better skin barrier by cutting water loss.
• Feels like nothing. It melts in without stickiness or tackiness — no gluey film under moisturiser or makeup.
• Recognised and vetted. An Allure Best of Beauty award winner, per the brand; vegan, gluten-free, cruelty-free, recyclable packaging.

How to use

1. Apply a few drops to clean skin, morning and evening.
2. Layer your other serums and moisturiser on top — hyaluronic acid works best when sealed in.
3. Finish mornings with SPF.

Questions

Where does it go in my routine?

Early — after cleansing and before heavier serums and moisturiser. The brand positions it as the serum that helps the rest of your skincare work harder, so let everything else sit on top of it.

Is it okay for acne-prone skin?

The INKEY List lists acne and blemishes among the concerns it suits, alongside dryness and fine lines — it's a lightweight hydrator rather than a rich, occlusive formula.
