Transform your skin while you sleep with Medik8 Sleep Glycolic™, a time-released overnight glycolic acid peel that delivers visible results without downtime. This high-strength yet gentle treatment exfoliates dead skin cells, boosts radiance, and helps smooth texture—perfect for dull, congested, or uneven skin tones.

KEY BENEFITS

 

  • Brightens dull skin overnight for a refreshed morning glow
  • Refines skin texture and minimises the appearance of pores
  • Improves skin tone and targets hyperpigmentation over time
  • Speeds up cell renewal, leaving your complexion smoother and more luminous
  • Non-drying formula with Medik8’s time-release technology for minimal irritation

KEY INGREDIENTS

 

  • Glycolic Acid (10%) – An AHA powerhouse that dissolves the bonds between dead skin cells to encourage exfoliation and renewal
  • Time-Release Technology – Controls the delivery of glycolic acid to avoid irritation
  • Tasmanian Pepperberry – A soothing botanical that reduces redness and inflammation
  • Glycerin – A hydrating humectant that prevents dryness and keeps skin supple

 

HOW TO USE

  • Use 2–3 times per week in the evening.
  • After cleansing, apply a pea-sized amount to dry skin.
  • Do not layer with other exfoliating acids or retinol.
  • Follow with a nourishing serum or moisturiser.
  • Always apply SPF the next morning.

Pro Tip: Start slowly (once a week) if you're new to acid exfoliants, and work up to more frequent use.

About a Good Skincare Routine


Skincare doesn’t need to be complicated—but it should be consistent. A strong routine balances:

  • Cleansing, opting for a double cleanse and using a Super Soft Microfibre Face Cloth
  • Targeted treatments like acids or serums. Am and Pm will differ, Vitamin C in the monrig & Retinols at night.
  • Hydration. Choose a moisturiser to suit your skin for day time or Night time. 
  • Protection (always SPF!)
  • Products like Medik8 Sleep Glycolic are powerful tools that slot into a good nightime skincare system to renew, resurface, and reveal your best skin over time.
