The formula

What makes the Hyaluronic Acid Serum different?

Hydration that stays put. Sodium Hyaluronate draws water into the skin's upper layers, while Propanediol boosts hydration and keeps the texture light. On dry skin in dry air, hyaluronic acid can pull moisture from the wrong place, so we added Jojoba Oil for a light seal. Apply to damp skin and follow with moisturiser.

Who it's for. Skin that feels tight, dehydrated or dull, including oily skin. It sits well with every other NKD Koala formula, morning and evening.

What to expect. With daily use, skin feels more comfortable and looks plumper. It is a daily hydrator, so use it morning and evening.

Application

How do I use the Hyaluronic Acid Serum?

  1. 01

    Cleanse first

    Start with a clean base using your Gentle Face Wash or Gel Cleanser.

    Leave skin slightly damp. HA works best on damp skin.

  2. 02

    Apply to damp skin

    Press 2 to 3 pumps into slightly damp skin. The moisture helps draw the HA into your skin.

    Apply before any other serums.

  3. 03

    Seal with moisturiser

    Always follow with a moisturiser to lock the hydration in. HA needs to be sealed.

    Use morning and evening for best results.

Always seal Hyaluronic Acid with a moisturiser. Without a seal it can draw moisture from the skin if the air is dry.

    A Lovely Addition to My Daily Ritual

    The face wash is lovely and gentle on my skin, and the hyaluronic acid serum is great – it absorbs well without leaving my skin feeling oily like some others I’ve tried. Overall, really happy with these products and would definitely recommend them!

About this formula

Questions about the Hyaluronic Acid Serum

How much hyaluronic acid is in the NKD Koala Hyaluronic Acid Serum?

1% Sodium Hyaluronate, the salt form of hyaluronic acid, with Propanediol, Jojoba Oil and Vitamin E.

Should I apply the NKD Koala Hyaluronic Acid Serum to damp or dry skin?

Damp. Press 2 to 3 pumps into slightly damp skin, then seal with a moisturiser. Hyaluronic acid draws water into the skin, so it works best with some moisture on the skin and a cream on top.

Can I use the Hyaluronic Acid Serum with vitamin C or retinol?

Yes. It layers well with both. Apply it first as the thinnest layer, then the Vitamin C Serum in the morning or the Retinol Serum at night, then moisturiser.

Does the Hyaluronic Acid Serum contain fragrance?

Yes. It contains Parfum, listed in the full ingredients on this page. If your skin reacts to fragrance, patch test before first use.

Is the Hyaluronic Acid Serum good for oily skin?

Yes. Oily skin can still be dehydrated, and this serum adds water rather than oil. It is light and layers under any moisturiser.

Why does my skin feel tight after hyaluronic acid?

Usually because it went onto dry skin or was not sealed. Apply it to damp skin and follow straight away with a moisturiser.

Can I use the Hyaluronic Acid Serum with the Anti-Acne Serum?

Yes. Apply the Anti-Acne Serum first and let it absorb, then the Hyaluronic Acid Serum, then moisturiser. The Acne & Clarity Ritual uses them together.

Can I use the Hyaluronic Acid Serum every day?

Yes, morning and evening. It is a daily hydrator rather than a treatment, so there is no need to build up.
