Description
Medik8 Sleep Glycolic is a leave-on overnight exfoliating treatment mask designed to resurface the skin while you sleep, helping to improve clarity, texture, and radiance by morning.
It’s formulated as a lightweight, non-rinse serum that works gradually through the night, making it one of Medik8’s more intensive at-home chemical exfoliation products.
What it does
- Gently resurfaces dull or uneven skin texture
- Helps unclog pores and reduce congestion
- Improves the look of fine lines and roughness
- Boosts brightness and overall skin radiance
- Supports a smoother, more refined complexion over time
Key ingredients
- Glycolic Acid (AHA) – a powerful exfoliant that dissolves dead skin cells on the surface to reveal fresher skin underneath
- Prickly Pear Extract – helps soothe and support skin recovery after exfoliation
- Soothing agents and humectants – help minimise dryness and maintain hydration while exfoliating
How it’s used
Applied in the evening after cleansing, it is left on overnight (like a serum or light treatment). It is typically used 2–3 times per week, depending on skin tolerance. Sunscreen is essential the following day due to increased sun sensitivity from glycolic acid.
Who it’s for
- Dull or uneven skin tone
- Congested or breakout-prone skin
- Early signs of ageing (fine lines, rough texture)
- People already comfortable with acid exfoliation (it’s more intensive than daily toners or mild acids)
