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.

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.

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.

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

First-time use

If you’re new to Sleep Glycolic, we advise performing a patch test at least 24 hours before first use. Learn how to patch test here.

Apply once and note the skin’s response, then use 2-3 times per week.

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.

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. We recommend Advanced Day Ultimate Protect.

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

A natural humectant which traps moisture within the skin to leave it hydrated and comfortable.

Frequently Asked Questions

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.
