Supercharged with 10% glycolic acid, 91% agreed Sleep Glycolic visibly resurfaced their skin* for a visibly brighter, smoother and more glowing complexion.

Key Benefits:
Radiant, Visibly Refined Skin
97% agreed Sleep Glycolic smoothed their skin surface*
95% agreed their skin tone was visibly brighter & illuminated after use*
*Proven via user trial on Sleep Glycolic. Tested over 4 weeks on 34 participants with ageing concerns.

Healthy Skin Barrier
Using innovative crystal encapsulation technology, it gradually releases glycolic acid into the skin throughout the night, without any of the redness and irritation that is often associated with peel formulas. This means the skin barrier remains balanced and comfortable during use.

Visibly Perfected Skin
Visibly resurfaces the skin texture, minimises the look of hyperpigmentation and smooths the appearance of fine lines and wrinkles. It also reduces congestion and the likelihood of new blemishes forming.

Complement Your In-Clinic Results
Sleep Glycolic can help to prolong the results of a facial/peeling course. It can also be used as an entry level, at-home peel for those who are nervous about their first peeling experience.

Key Ingredients:
10% Active Glycolic Acid
The most powerful AHA, glycolic acid has the smallest particle size of all of the AHAs. Working to break down the bonds between dead skin cells, so that they can be easily exfoliated to reveal newer, fresher skin cells underneath for a visibly smoother, brighter and decongested complexion. This active is contained within a cyclodextrin-based shell, to ensure that it is gradually released into the skin throughout the night to prevent irritation while prolonging the visible results.

Korean Clover Extract
Working together with glycolic acid, it supports the skin’s natural overnight hydration and repair process. Helping to maintain the skin’s natural barrier, it reduces the potential for irritation.

Glycerin
A natural humectant, glycerin traps moisture within the skin to leave it comfortable and hydrated.

Directions

Step 1
After cleansing in the evening, smooth a pea-sized amount of Sleep Glycolic onto the face, neck and décolletage - avoiding the eye area. Some slight skin tingling is normal.

NOTE: For use 2-3 times per week.

Step 2
Follow with other serums and night moisturiser. Leave on overnight. As Sleep Glycolic is directly active on your skin, it should be the second step in your evening skincare routine (after cleansing). Layer all other serums and moisturisers on top.

Step 3
Always wear sunscreen the next day after using Sleep Glycolic. Patch testing prior to use is advised.

How to Layer Sleep Glycolic
AM: Apply Sleep Glycolic after cleansing. Follow with your target serum, Crystal Retinal and finally, your moisturiser.

Rated 4 out of 5 by from Good value So far I feel its been ok but need a bit more time to say whether or not what the products claim to say what they do (help to prevent wrinkles) have worked. Im a mature women who has a few lines & are concentrating on these to see the difference.

Rated 5 out of 5 by from Sleep glycolic genius I love my Sleep Glycolic. It's great for giving my skin some overnight treatment which is noticeable in the morning when my face feels smoother in texture and blemishes appear blurred. It's a great twice weekly treat.

Rated 5 out of 5 by from Easy to use and good results Used for the first time last night. Today my skin is much smoother and, I’m happy with the outcome. I layered it with the Retinal and it went well, I was a bit worried but it all worked out as I’d hoped. I'm looking forward to seeing how much my skin improves using the glycolic sleep serum.

Rated 3 out of 5 by from Sleep Glycolic I’m honestly not sure about this product yet (I am a top tier purchaser and very loyal to Medik8). This is the first and only product I am on the fence with in Medik8’s range. I have only used a few times and nowhere near to using up the small tube so I don't think I have given it enough time. I will continue to use and place another review once I’ve finished the tube. It stings very slightly on my skin, maybe that has made me less confident using it. There is definitely nothing wrong with it, I just haven’t noticed a difference in my skin using it but I also haven’t been consistent.

Rated 5 out of 5 by from Great Product I use this on alternate nights with retinal, there is no irritation & I wake up with bright, soft skin. A little goes a long way. I am very happy with it.
