How to apply
- Use this exfoliant product in your PM routine once a week to start, increasing frequency only if your skin tolerates it well. Always apply SPF the next morning to protect your skin.
- Apply this exfoliant product after cleansing and toner, but before your moisturizer. This ensures the best absorption into your skin.
- Gently press 2-3 drops of the exfoliant product into your face, avoiding any rubbing. Let it absorb for a minute before moving to the next step.
- Apply this exfoliant product on completely dry skin to get the best results. This helps your normal skin accept the product smoothly.
- Avoid the sensitive eye area while using this exfoliant product. Do a patch test before your first use and avoid mixing it with strong acids.

Questions and answers
How well does Medik8 Sleep Glycolic work for mature skin?

Which ingredients make this exfoliant a good fit for mature skin?
Glycolic acid makes this exfoliant a good fit for mature skin by helping smooth wrinkles and fine lines, while glycerin supports skin health by providing essential hydration. An exfoliant for mature skin needs exceptionally safe formulas, high concentrations of potent antioxidants, and hydrating ingredients that target fine lines and wrinkles while keeping the skin calm.

Where does this exfoliant go in a skincare routine for mature skin?
This exfoliant treatment goes in the evening routine after cleansing and before moisturizing. To better fit mature skin, this type of product needs ingredients that provide deep hydration and antioxidants alongside gentle exfoliating acids.
Can I use this exfoliant with retinol, and in what order?
It is best to use this exfoliant on separate nights from your retinol to help prevent dry or irritated skin.

Start using this exfoliant once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. This approach helps smooth fine lines while keeping your skin calm.

Is this exfoliant fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
