Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate exfoliation for your dry skin due to the presence of glycolic acid, which promotes skin renewal, while glycerin provides some humectant action to aid hydration.
  • The formula lacks sufficient emollient ingredients like caprylic capric triglyceride to fully address dryness, and the exfoliation benefits are mostly supportive rather than directly targeting dry or flaky skin.
  • The product is safe for your dry skin as it contains no prohibited or harsh ingredients that would cause irritation.

How to apply

  • Use this exfoliant as part of your PM routine once a week, increasing slowly to twice a week if your dry skin tolerates it well. Always remember to apply SPF every morning to protect your newly smoothed skin.
  • Apply the exfoliant after cleansing and toning, but always before your rich moisturizer.
  • Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute. Avoid rubbing to prevent any irritation on flaky areas.
  • Apply the product directly to dry clean skin to ensure the best possible tolerance for your dry type. This helps address flaky patches without causing extra stress.
  • Avoid the sensitive eye area and do a quick patch test before your very first use. Do not mix this with other strong acids or retinoids on the same night.

Questions and answers

How well does Medik8 Sleep Glycolic work for dry skin?

Medik8 Sleep Glycolic works moderately well for dry skin, offering some renewal and hydration through glycolic acid and glycerin, though it lacks enough rich softening ingredients to fully address dryness. An exfoliant treatment for dry skin needs soothing, highly hydrating ingredients like ceramides, niacinamide, or peptides, alongside strong barrier support.

Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this exfoliant a good fit for dry skin?

Glycolic acid helps renew dry skin by providing moderate exfoliation, while glycerin adds moisture to keep skin hydrated. Because this product is only an average fit for dry skin, an exfoliant of this type needs rich moisturizing and soothing ingredients like ceramides, niacinamide, or peptides to thoroughly nourish dry skin and support the skin barrier.

Clinical, Cosmetic and Investigational Dermatology, 2017

What does Glycolic Acid do for dry skin?

Glycolic acid helps smooth and soften dry skin by speeding up the shedding of older surface cells. Because it can also cause the skin to lose more moisture, dry skin needs extra hydrating ingredients like glycerin or hyaluronic acid alongside it to keep the skin comfortable.

Acta Dermato-venereologica, 1995

What does Glycerin do for dry skin?

Glycerin helps dry skin by drawing in moisture and keeping it locked in, which makes the skin feel much softer and smoother. It also supports your natural skin barrier to stop water from escaping easily. A product for dry skin needs extra ingredients like hyaluronic acid and soothing plant extracts to truly calm and hydrate dry patches.

Clinical, Cosmetic and Investigational Dermatology, 2017The British Journal of Dermatology, 2008

Where does it go in a skincare routine for dry skin?

This treatment goes in the evening routine after cleansing and before your moisturizer. Lovi routines start exfoliating treatments once a week, and you may slowly use it more often if your skin handles it well.

Can I use it with retinol, and in what order?

You can use this treatment with retinol by applying them on separate nights to help prevent irritation on dry skin. Dry skin of this type needs rich moisturizing ingredients like plant oils and butters to lock in hydration and deeply soften rough patches.

How often should I use it?

Start by using this exfoliant treatment once a week in the evening, and if your dry skin handles it well, you may carefully use it more often. A dry skin routine needs rich smoothing ingredients and soothing hydration to keep your skin soft and comfortable.

Can this exfoliant clog pores, cause breakouts or purging for dry skin?

This exfoliant is unlikely to clog pores or cause breakouts on dry skin, and any skin clearing or purging is minimal since the glycolic acid provides only moderate exfoliation. The formula is safe for your skin with a low chance of irritation, though dry skin generally needs richer soothing oils and deep hydration ingredients to feel fully comfortable.

Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
