✓ 10% Time-Release Glycolic Acid | ✓ 97% Agreed It Smoothed Their Skin Surface | ✓ Overnight At-Home Peel Without the Redness

Medik8 Sleep Glycolic is Medik8's overnight at-home peel: a leave-on 10% glycolic acid formula in time-release crystal encapsulation, so the acid is delivered gradually through the night for noticeably brighter, smoother, decongested skin by morning - without the redness and irritation usually associated with peel formulas. Used two or three nights a week, it is the glycolic acid peel for dull, uneven, congested skin that wants a visible glow fast.

Glycolic acid has the smallest molecule of all the AHAs, which is what makes it the most powerful: it breaks down the bonds holding dead cells to the surface so they shed to reveal fresher skin beneath. The problem has always been the sting. Medik8 holds the 10% dose inside a cyclodextrin shell that releases it slowly overnight, so the barrier stays comfortable and the visible effects last longer, while Korean clover extract supports the skin's overnight renewal and hydration and glycerin keeps it comfortable. In Medik8's 4-week user trial on 34 participants with ageing concerns, 97% agreed Medik8 Sleep Glycolic smoothed their skin surface, 95% agreed their tone was visibly brighter and illuminated and 91% agreed it visibly resurfaced their skin.

Leave-on and layerable - serums and night cream go straight on top
Pairs with Crystal Retinal: Medik8 says glycolic acid and retinal enhance each other's smoothing and brightening benefits
Alcohol free, paraben free, no artificial fragrance and certified by The Vegan Society

Best For

Dull, lacklustre skin that wants a fast visible glow
Uneven texture, rough patches and fine lines
Congested skin and visible pores
Dark spots and uneven-looking tone
Prepping skin before an event, or prolonging in-clinic peel results

Choose Medik8 Sleep Glycolic if you want a stronger, twice-weekly resurfacing step; for everyday gentle exfoliation, Press & Glow is the daily option, and you do not need both on the same night.

Becci is a registered aesthetics nurse with more than two decades in specialist skincare and medical aesthetics, and clinic glycolic peels are something she knows inside out, so clients ask her honestly whether at-home versions work. Medik8 Sleep Glycolic is the one she recommends: a proper 10% dose made usable at home by time-release delivery, strong enough that she sees the difference and gentle enough that clients keep using it.

FAQS

Is Medik8 Sleep Glycolic a good at-home glycolic peel for beginners? +

Yes - Medik8 describes it as an entry-level at-home peel for anyone nervous about a first peel, because the 10% glycolic acid is time-released overnight rather than hitting the skin at once. In the brand's 4-week user trial 97% agreed it smoothed their skin surface and 95% agreed their tone looked brighter. Patch test, use it once to see how your skin responds, then build to two or three nights a week.

What is the difference between Sleep Glycolic and Press & Glow? +

Press & Glow is an everyday 5.5% PHA exfoliating toner for bright, glowing skin that fits into every routine. Sleep Glycolic is a more intense 10% glycolic acid overnight peel for advanced signs of ageing or stubborn texture and congestion, designed for a couple of nights a week - and ideal for prepping skin before an event. Medik8 says you do not need Press & Glow on the nights you use Sleep Glycolic.

Can I use Medik8 Sleep Glycolic with Crystal Retinal? +

Yes - Medik8 actively recommends the pairing, saying glycolic acid and retinal enhance each other's smoothing, brightening and decongesting benefits. Apply Sleep Glycolic straight after cleansing, then Crystal Retinal, then moisturiser. If your skin is new to both, settle into one before adding the other.

Can I use Sleep Glycolic with Press & Glow or Press & Clear? +

Not on the same night. Medik8 does not recommend layering exfoliating acids, so simply swap your everyday acid toner out on Sleep Glycolic nights: Press & Glow in the morning, Sleep Glycolic that evening, Press & Glow again the next morning. Wash-off acid cleansers such as Surface Radiance Cleanse are fine alongside it.

How often should I use Sleep Glycolic? +

Apply it once and note your skin's response, then use it 2-3 nights a week. It is not designed for nightly use - the everyday exfoliation job belongs to Press & Glow.

Can I use Sleep Glycolic in the morning? +

No. Medik8 advises against daytime use because glycolic acid can make skin more sensitive to the sun. Use it in the evening after cleansing and always wear sunscreen the next morning.

Will Sleep Glycolic make my skin red or peel? +

It is designed not to. The crystal-encapsulated glycolic acid is released gradually overnight so the barrier stays comfortable, and Medik8 built it specifically to avoid the redness and peeling associated with traditional peels. Slight tingling on application is normal; if you get more than that, drop back to once a week and build up.

Does Sleep Glycolic replace my serums or night cream? +

No - it is a leave-on peel step, not a moisturiser. Apply it second (after cleansing), then layer your usual serums and night moisturiser on top. A pea-sized amount covers the face, neck and décolletage, and Medik8 counts around 60 uses per 30ml tube.

Can I use Medik8 Sleep Glycolic during pregnancy or while breastfeeding? +

Sleep Glycolic contains 10% glycolic acid, an AHA that midwives are commonly asked about. Medik8 does not publish formal pregnancy or breastfeeding guidance for this product: as a cosmetics company it says it cannot advise on medical conditions and asks customers to discuss the ingredient list with their GP or midwife before use. Please check with your midwife or GP first.
