How It Works
Sleep Glycolic is the Medik8 approach to at-home glycolic acid.
Glycolic acid is the most powerful of AHAs (alpha hydroxy acids). 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 oversensitize the skin, and impair the natural skin barrier function. 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 on contact with the skin. The encapsulation gradually delivers the high strength exfoliating acid into the skin overnight to minimize any potential for discomfort. With a total 10% active acid, Sleep Glycolic has the power to effortlessly deliver exfoliation benefits to the skin. This is ultimate high-strength glycolic acid, 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 moisturizer. Leave on overnight.
Always wear sunscreen the next day after using Sleep Glycolic.
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 moisturizers over this.
Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
An exfoliating AHA, glycolic acid helps to slough off dead skin cells to promote a smoother skin appearance.

As a natural humectant, glycerin helps to trap water within the skin to leave it feeling hydrated and comfortable.
Native to South Korea, Korean Clover Extract works alongside glycolic acid to support the skin’s natural overnight processes. It can help to support the natural skin barrier, leaving skin brighter and healthier-looking.Full Ingredients
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 have an effect on stubborn skin concerns. In Sleep Glycolic, we have optimized 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 any potential for discomfort when using the formula, instead helping to maintain a healthy skin barrier.”
