Product Description

Achieve a noticeably smoother, brighter and decongested complexion with Medik8’s Sleep Glycolic. This at-home AHA (alpha hydroxy acid) peel treatment delivers quick overnight results - 91% felt Sleep Glycolic helped to achieve the appearance of beauty sleep.

Supercharged with 10% glycolic acid, 91% agreed Sleep Glycolic visibly resurfaced their skin* for a visibly brighter, smoother and more glowing complexion.
*Proven via user trial on Sleep Glycolic. Tested over 4 weeks on 34 participants with ageing concerns.

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 5 out of 5 by from Great Addition to my Routine [This review was collected as part of a promotion.] Love the slight tingling feeling this product gives when applying, I can defintely see a difference in my skin since I started using it

Rated 5 out of 5 by from Really helped with my texture [This review was collected as part of a promotion.] I didn't know if this would work but having used it a couple of times it's really helped with the uneven texture on my skin, especially my forehead. I don't know Medik8 have done it but it's a gentle but powerful exfoliant so you don't need to use it as often hence why it will last you a long time!

Rated 5 out of 5 by from Very good with my Sensitive Skin [This review was collected as part of a promotion.] I have now been using Medik8 products for the last 6 months now, been really happy with the products and keep adding medik8 products into my regime, I use this product after cleansing but before the rest of my routine twice a week and works really well with the Retinal and night moisteriser, I have noticed a big difference in my skin, complexion, fine lines and Hyperpigmentation, I would definitely recommend this product and suits my Sensitive skin which is also a bonus.

Rated 5 out of 5 by from Crystal retinal [This review was collected as part of a promotion.] After a lifetime of trying top high end cosmetics I've finally found the holy grail. Medic 8 products actually work they deliver as promised and some. Dont hesitate or waste any more time and money on any other products Wish I'd found them years ago

Rated 5 out of 5 by from Beauty sleep in a tube [This review was collected as part of a promotion.] Love this!
