Awaken to smoother, glowing skin with Medik8 Sleep Glycolic. This professional-strength at-home overnight facial works in tandem with the skin's natural nighttime repair process to transform the look of your skin while you sleep. Formulated with encapsulated 10 percent glycolic acid, this nighttime peel exfoliates slowly throughout the night, meaning you can say goodbye to that uncomfortable stinging and flaking you normally associate with acid skincare, while still targeting visible signs of ageing and blemishes.

One of the best glycolic acid peels around, it is made to be comfortable and effective and to improve the health of your skin, the Medik8 glycolic acid peel at home is safe for use once a week or twice weekly (depending on your skin type) in place of your regular toner. You'll see a noticeable glow from the first morning, and that glow will also build over time. While it's great for most skin types, it's not recommended for very sensitive or reactive skin types, so if you think you are in that category, a patch test is advised. If you're dealing with dullness, fine lines, dark spots, or uneven skin texture, this is the perfect pick.

What's Inside? Key Ingredients of Medik8 Sleep Glycolic Overniight Peel

10 % Glycolic Acid (Encapsulated) — This alpha hydroxy acid exfoliates deep within pores and across the skin's surface to refine texture, fade pigmentation, smooth fine lines and encourage skin renewal. The encapsulation helps release the acid slowly, reducing irritation.
Cyclodextrin — A sugar‑based molecule used to encapsulate glycolic acid, creating a controlled release that minimises tingling or stinging while maintaining effectiveness.
Glycerin — A moisture‑binding humectant that draws water into the skin, keeping it hydrated and comfortable throughout the treatment process.
Korean Clover Extract (Lespedeza Capitata) — A skin‑soothing botanical known for helping the skin bounce back from daily stress while supporting overnight repair and clarity.
Dimethicone — A silky silicone that forms a breathable barrier to lock in hydration and smooth skin texture.
Caprylic/Capric Triglyceride — Derived from coconut oil and glycerin, it softens the skin and improves texture without clogging pores.

Our Review: Medik8 Sleep Glycolic Peel Results & Feedback

We believe that Medik8 Sleep Glycolic is one of the cleverest exfoliators available for at‑home use. Firsthand, we've witnessed how it brings dullness to a speedy end and smoothes over rough patches. We consistently hear from customers who wake up looking more radiant and with a smoother complexion after just one night's use. It's our belief that it's the encapsulated glycolic acid that makes all the difference, strong enough to provide that post‑facialglow but super gentle for regular use without any redness or peeling.

We know it's particularly popular among women addressing pigmentation or those looking to maintain results in between salon visits. From using it ourselves, we know that it just leaves the skin looking so much more even and glowy, especially when followed with a basic moisturiser and sunscreen daily. In our view, it really does make a difference. We also love that it's professional‑grade without impeding your routine (you only apply it once per week), and it's fragrance‑free, so it's less likely to make your skin red and reactive.
