How It Works
Sleep Glycolic is the Medik8 approach to at-home glycolic acid.
The smallest of the AHAs (alpha hydroxy acids), glycolic acid can penetrate the deepest into the skin. As a result, glycolic acid can address more stubborn skin concerns such as uneven texture and a lacklustre complexion.
High strength at-home glycolic acid products (most commonly daily toners) are readily available and are often directed for regular, everyday use. This has the potential to cause irritation, and an impairment to the skin barrier. That’s why at Medik8 we believe that occasional use of glycolic acid is best – not daily. Leave daily acids to super-gentle PHAs (polyhydroxy acids, found in Press & Glow).
Instead, Sleep Glycolic takes an innovative approach to at-home glycolic acid, harnessing the powerful exfoliating effects of glycolic acid in a bi-weekly treatment without the downsides.
Glycolic acid is encapsulated in a crystal cyclodextrin ‘shell’ that is slowly broken down upon contact with skin enzymes. The encapsulation gradually delivers the high strength exfoliating acid into the skin overnight to reduce the potential for irritation.
With a total 10% active acid, the glycolic acid is able to easily penetrate into the skin, improving the end results. This is ultimate glycolic power, without the downsides.
How To Use
For use 2-3 times a week.
After cleansing in the evening, smooth a pea-sized amount of Sleep Glycolic onto the face, neck and décolletage, avoiding the eye area.
Follow with other serums and night moisturiser.
Leave on overnight.
Always wear sunscreen the next day after using Sleep Glycolic.
Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
A note on layering; as Sleep Glycolic is a direct acid, it should be the first step in your evening skincare routine. Layer all other serums and moisturisers over this.

With the smallest particle size of all the AHAs, glycolic acid is the most powerful. It works to breakdown bonds between dead skin cells so they are easily exfoliated away to reveal fresher, newer skin cells beneath – for visibly brighter and smoother skin.
A cyclodextrin-based shell which encapsulates the glycolic acid. On the skin this slowly breaks down, delivering the glycolic acid gradually into the skin to reduce irritation.
An effective humectant ingredient, glycerin draws moisture to itself like a magnet, leaving skin feeling hydrated, soft and supple.

The Science Behind
“The effectiveness of exfoliating acid products depends heavily on two factors; acid concentration and the pH of the formula. A low pH is crucial to activate acids within a cosmetic formula. Every exfoliating acid (AHA or BHA) can exist in an active form, or an inactive form. Only when an acid is in its active form, will it be able to make its way easily into the skin to have an effect on stubborn skin concerns like hyperpigmentation. In Sleep Glycolic, we have optimised our active acid content by lowering our pH to 3.5 – to achieve an active acid value of 10%. This gives us a truly powerful glycolic acid formula. Crystal encapsulation and bi-weekly usage helps us to control this power, reducing irritation from the formula to maintain a healthy skin barrier.”
