Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation due to the presence of glycolic acid, which promotes skin renewal but may not fully address your dry or flaky skin concerns.
- Glycerin provides humectant action suitable for dry skin, yet the formula lacks sufficient emollient ingredients like caprylic capric triglyceride to fully combat dryness.
- The product is safe for your dry and sensitive skin, as it contains no harsh or prohibited ingredients that could cause irritation.
How to apply
- Use your exfoliant PM once a week to help with dryness. Start ⏳3 times a week only if your sensitive skin tolerates it well.
- Apply the exfoliant after cleansing and toning, but always before your favorite moisturizer .
- Gently press 2-3 drops of the exfoliant into your skin and avoid any rubbing. Let it absorb ⏱ for a minute before layering.
- Since your skin is reactive and sensitive, apply the exfoliant on completely dry skin for better tolerance.
- Always do a patch test before your first use and avoid the delicate eye area .

Questions and answers
How well does Medik8 Sleep Glycolic work for dry sensitive skin?
Medik8 Sleep Glycolic is an average fit for dry sensitive skin because while it safely encourages skin renewal and offers some moisture, it may not fully address flaky areas. An exfoliant treatment for this skin type needs rich hydrating and nourishing ingredients, such as ceramides and multiple forms of vitamin C, to deeply lock in moisture and protect the skin barrier.
Which ingredients make this exfoliant a good fit for dry sensitive skin?
Glycerin helps keep dry skin hydrated, while glycolic acid promotes skin renewal without causing irritation. However, dry sensitive skin needs an exfoliant of this type to also include rich moisturizing ingredients and skin-softening oils to fully combat dryness and smooth flaky areas.
What does Glycolic Acid do for dry sensitive skin?
Glycolic acid can be too harsh for dry sensitive skin and may cause irritation, so this skin type needs gentle calming ingredients and deeply nourishing moisturizers to keep the skin barrier safe and smooth.
Acta Dermato-venereologica, 1995The British Journal of Dermatology, 1997
What does Glycerin do for dry sensitive skin?
Glycerin helps dry sensitive skin by drawing moisture into the skin and keeping it there, making the skin soft and smooth. It is very gentle and unlikely to cause irritation while improving how well the skin holds onto water. This type of skin needs ingredients that boost hydration and repair the barrier without causing stinging.
Clinical, Cosmetic and Investigational Dermatology, 2017The British Journal of Dermatology, 2008
Where does it go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine once a week to start, as this skin type needs gentle exfoliation paired with rich skin-softening oils and deep hydrators to effectively smooth dry and flaky areas.
Can I use this exfoliant with retinol, and in what order?
It is best to avoid using this exfoliant on the same night as your retinol to prevent irritation on dry and sensitive skin. Instead, alternate nights between the two treatments or use retinol in the evening and this exfoliant on a separate weekly night.
How often should I use it?
Start using this treatment once a week in your evening routine, and if your skin feels comfortable and tolerates it well, you may carefully use it more often. A product of this type for dry sensitive skin needs gentle renewing ingredients paired with rich, soothing and softening ingredients to keep your skin smooth and comfortable.
Can this exfoliant clog pores, cause breakouts or purging for dry sensitive skin?
This exfoliant is unlikely to clog pores or cause breakouts on dry sensitive skin, as it contains no heavy oils or common pore-clogging ingredients. Glycolic acid may cause mild skin renewal or light flaking at first, but the formula is generally safe and well-tolerated.
Is it fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
What the research says
