Name: Sleep Glycolic 30ml
Rating: 4.9 (380 reviews)

KEY BENEFITS

Radiant, Visibly Refined Skin

Sleep Glycolic removes dead skin cells from the skin's surface to reveal a visibly smoother and glowing complexion, with a more even tone and texture.
Healthy Skin Barrier

Sleep Glycolic uses innovative crystal encapsulation technology to gradually deliver glycolic acid into the skin throughout the night. This means the skin barrier remains comfortable and balanced during use.
Visibly Perfected Skin

Visibly resurfaces the skin texture, smooths the appearance of fine lines and wrinkles, and minimises the look of hyperpigmentation. It also reduces congestion and the likelihood of blemishes forming.
Complement Your In-Clinic Results

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

HOW TO USE

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.

KEY INGREDIENTS

10% Active Glycolic Acid

With the smallest particle size of all the AHAs, glycolic acid is the most powerful. It works to break down the bonds between dead skin cells, so they can be easily exfoliated away to reveal fresher, newer skin cells beneath. The result is visibly brighter, smoother and decongested skin. This active is contained within a cyclodextrin-based shell (pronounced 'sy-clo-DEXtrin'). This ensures its gradual release into the skin overnight to prevent irritation while prolonging the visible effects.
Korean Clover Extract

Works alongside glycolic acid to support the skin’s natural overnight repair and hydration processes. It also helps to maintain the natural skin barrier; reducing the potential for irritation.
Glycerin

By gently drawing water to itself from the lower layers of the skin, glycerin leaves skin nourished and replenished of moisture for a soft and supple complexion.

THE SCIENCE BEHIND THE FORMULA

Sleep Glycolic harnesses the powerful benefits of glycolic acid - without the common downsides like redness and skin peeling.

DANIEL ISAACS Chief Product Officer

The effectiveness of exfoliating acid products depends on 2 main things: how much acid is in the product (i.e. its %) and how acidic it is (i.e. its pH). Having a low level of acidity is important to make the acid work in the product. Exfoliating acids, like AHA or BHA, can be either active or inactive. Only when they are active, can they go into your skin and help with stubborn skin concerns such as hyperpigmentation. In Sleep Glycolic, we made sure our acid is active by making the product more acidic than most with a pH of 3.5 to ensure it delivers 10% of active acid. This makes our glycolic acid product very powerful. To control this power and prevent skin irritation, we use crystal encapsulation to release it slowly throughout the night and recommend using it twice a week to keep your skin healthy.

FAQS

What's the difference between Sleep Glycolic and Press & Glow?

+
Press & Glow is an everyday exfoliating toner for bright, glowing skin that fits effortlessly into every skincare routine. Sleep Glycolic is a more intense treatment for advanced signs of ageing or stubborn skin concerns; designed to be used a couple of times a week. It is also ideal for prepping the skin for an event (wedding, party etc). You do not need to use Press & Glow on days you use Sleep Glycolic.
Can you use Sleep Glycolic with other exfoliating acids like Press & Glow or Press & Clear?

+
No. We don't recommend layering exfoliating acids on top of one another. Simply switch out your everyday exfoliating acid (such as Press & Glow) on the days you want to use Sleep Glycolic in your evening routine. For example, you can use Press & Glow in your AM regime, Sleep Glycolic in the PM, then Press & Glow in the following AM regime.
"Can I use Sleep Glycolic alongside a wash-off acid cleanser? "

+
Yes. Sleep Glycolic can be used alongside wash-off cleansers that contain acids such as Surface Radiance Cleanse.
Can I use Sleep Glycolic during pregnancy?

+
As a cosmetics company, we are unable to provide product advice in relation to medical conditions such as pregnancy. We would recommend discussing the ingredients with your GP or midwife before use.
Can I use Sleep Glycolic in the morning?

+
We do not advise using Sleep Glycolic during the day, as glycolic acid can make skin more sensitive to sun damage. Instead, use 2-3 times a week after cleansing in the evening. Follow with other serums and moisturiser. Always use a sunscreen the morning after using Sleep Glycolic.

Q: Can I use Sleep Glycolic, Liquid Peptides Advanced MP and Crystal Retinal (I'm using 24) on the same routine? If yes, in what order and how long do I need to wait between each step?

Medik8

04/07/25

A: Hi Lily, using Sleep Glycolic, Liquid Peptides Advanced MP and Crystal Retinal together is absolutely fine. Provided you have completed the phasing in period for Crystal Retinal and you know your skin is comfortable with it, you can use Sleep Glycolic 2-3 evenings per week, applying it right after cleansing, followed by your other products in their usual order.

Q: Hi, can I use this on the same night as a retinoid?

Medik8

03/20/25

A: Hi Brandon, you certainly can. We would just recommend ensuring that your retinoid is phased into your routine before introducing Sleep Glycolic. Sleep Glycolic would be applied after cleansing and before your other products.

Q: Can I use sleep glycolic after an LED mask?

Medik8

A: Hi Soraya, our Sleep Glycolic has not been specifically tested with LED masks, but we would advise speaking with the manufacturer of the mask to find out what products would be compatible.

Q: Can I use crystal retinal at the same time as sleep glycolic?

Medik8

10/16/24

A: Hi Annie, we love this question! Yes, you can definitely use our Sleep Glycolic with Crystal Retinal; this will help to boost results. We just advise you not to add Sleep Glycolic to your routine until you have fully phased your Crystal Retinal into it (using it every night, with no irritation). For best results, apply Sleep Glycolic after cleansing 2-3 nights a week, before Crystal Retinal.

You can find more helpful information about our Sleep Glycolic here - medik8.com/pages/sleep-glycolic-faqs

We recommend choosing one leave-on acid (Press & Glow, Pore Minimising Tonic, Blemish Control Pads) to use in a single routine—either AM or PM. For example, if you regularly use Blemish Control Pads twice a day as per our directions of use and want to use Press & Glow, we recommend you alternate which one you use in your morning and nighttime routine.We hope this helps! Thanks, Medik8.
