Sleep Glycolic is an at-home AHA (alpha hydroxy acid) peel which can deliver fast results while you sleep, with zero downtime. This bi-weekly treatment can transform dull, uneven textured skins who want visibly brighter, smoother skin - fast.

Harnessing a true free glycolic acid value of 10% for enhanced penetration results, Sleep Glycolic effortlessly leaves the complexion visibly brighter, smoother and decongested.

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% free 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.

Sleep Glycolic delivers fast resurfacing results. The glycolic acid formula helps to slough off dead skin cells to reveal a visibly glowing complexion. The at-home peel effortlessly smooths the appearance of fine lines and wrinkles, while restoring the skin’s natural luminosity as you sleep. The encapsulated glycolic acid is time-released into the skin overnight, to gently deliver the high acid concentration.

After cleansing in the evening, apply before vitamin A and follow with a night time moisturiser. Always use SPF the morning after, as glycolic acid can make skin more sensitive to the sun. Use 2-3 times a week.

A powerful AHA, glycolic acid helps to visibly resurface and exfoliate the outermost layers of skin, to leave a brighter and clearer complexion. By lowering the pH of our formula to 3.5, we have been able to achieve a true free, active acid value of 10%.


Cyclodextrin encapsulates glycolic acid. When applied topically, the encapsulation is broken down by skin enzymes, allowing the glycolic acid to be slowly released into the skin, minimising irritation.


Korean clover extract works alongside the glycolic acid by supporting the skin's natural overnight repair and hydration process. It can help to maintain the natural skin barrier; leaving skin brighter, healthier and in sync.


A natural humectant, glycerin helps to draw water into the skin, leaving the complexion hydrated, supple and visibly smoothed.
