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.
