Masks guide

Using an overnight AHA mask

The Sleep Mask uses 2% glycolic acid and 1% lactic acid, with lactobionic acid, to exfoliate the surface of the skin overnight, for skin that looks smoother and brighter with regular use. It is a leave-on mask: apply it as the last step of your evening routine and rinse it off in the morning.

Start two nights a week after cleansing, on dry skin, and build up to three if your skin is comfortable. Skip it on nights you use the Retinol Serum, the Anti-Acne Serum or the Gel Cleanser With Scrub, and wear SPF 30 or higher every morning, because exfoliating acids can make skin burn more easily.

The lactobionic acid is derived from dairy, so the Sleep Mask is the one NKD Koala formula that is not vegan. It contains fragrance, like every formula we make. You will also find it in the Weekly Reset Ritual and the Advanced Anti-Aging Ritual.

Common questions

How often should I use an overnight AHA mask?

Start with two nights a week and build up to three if your skin feels comfortable. Do not use it every night.

Can I use the Sleep Mask with retinol?

Not on the same night. Alternate them, with a rest night if your skin feels dry or tight.

Is the Sleep Mask vegan?

No. It contains lactobionic acid derived from dairy. Every other NKD Koala formula is vegan.
