This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other products fit it better.

## Why this fit

- Offers moderate exfoliation for your normal skin due to glycolic acid, which helps with skin renewal but may also cause irritation for your sensitive skin.
- Glycerin provides humectant action beneficial for skin balance, though the concentration of glycolic acid is not ideal for addressing your specific concerns of redness and irritation.
- The product is generally safe for your sensitive skin, with a low risk of irritation.

## What the research says

- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Regular application of cosmetic submicron emulsions and gels containing hydroxypropyl-beta-cyclodextrin showed no statistically significant effects on skin barrier function and observed physiological skin parameters in 15 healthy human subjects over four weeks, indicating good skin tolerability. ([International Journal of Cosmetic Science, 2021](https://pubmed.ncbi.nlm.nih.gov/33236374/))
- Repeated short-contact 70% glycolic acid peels provided superior results in atrophic acne scars compared to daily low-strength glycolic acid cream or placebo in 58 women over 24 weeks. ([International Journal of Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/11095203/))
- Serial glycolic acid peels combined with a modified Kligman formula significantly reduced facial PIH severity in Indian patients compared to the modified Kligman formula alone. ([Dermatologic Surgery, 2017](https://pubmed.ncbi.nlm.nih.gov/28114204/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))
- The circadian clock component PER represses MMP-1 expression via the cAMP signaling pathway and mediates the MMP-1 suppression induced by Lespedeza capitata extract in HaCaT keratinocytes. ([Molecules, 2018](https://pubmed.ncbi.nlm.nih.gov/29570674/))
- Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups. ([Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/))
- Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms. ([Clinical and Experimental Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17137484/))
- Externally applied substances such as ceramides, hyaluronic acid, licorice extracts, dimethicone, petrolatum, and paraffin wax treat skin disease resulting from damage to the skin barrier. ([Clinics in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22507050/))
- Topical retinoic acid-beta-cyclodextrin complex formulations at 0.025% showed greater acne improvement scores (4.0-4.1) and lower irritation than a commercial 0.05% retinoic acid gel (score 3, with side effects in all patients) after 3 months in 66 patients with acne vulgaris. ([Journal of the European Academy of Dermatology and Venereology, 2004](https://pubmed.ncbi.nlm.nih.gov/15196153/))
- Tretinoin cyclodextrin complex demonstrated an antiwrinkle effect equal to that of conventional tretinoin with more moderate irritant reactions in photoaged patients. ([Aesthetic Plastic Surgery, 2012](https://pubmed.ncbi.nlm.nih.gov/22538278/))
- Binary systems of trans-resveratrol with polyethylene glycol or beta-cyclodextrin enhanced its antioxidant activity and in vivo skin anti-aging effects compared to trans-resveratrol alone in human keratinocytes and volunteers.

## Questions and answers

### How well does Medik8 Sleep Glycolic work for sensitive skin?

Medik8 Sleep Glycolic works moderately well for your sensitive skin because glycolic acid helps with skin renewal, though it may cause irritation. Glycerin balances hydration, but an exfoliant for sensitive skin needs soothing antioxidants, calming agents for redness, and hydrating ingredients without any risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this exfoliant a good fit for sensitive skin?

Glycerin helps keep sensitive skin balanced by drawing in moisture, while dimethicone protects the skin barrier and reduces the likelihood of irritation. However, because this product contains glycolic acid, it needs soothing ingredients like niacinamide, antioxidants, and hydrating agents to properly calm redness and protect sensitive skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Glycolic Acid do for sensitive skin?

Glycolic acid can be too harsh for sensitive skin, leaving it dry and irritated, so this type of skin needs a gentler exfoliating ingredient and calming plant extracts to keep the skin barrier safe and comfortable.
Sources: [Cutaneous and Ocular Toxicology, 2022](https://pubmed.ncbi.nlm.nih.gov/35920724/)

### What does Glycerin do for sensitive skin?

Glycerin helps keep sensitive skin soft and deeply hydrated while supporting the skin barrier. It is unlikely to cause irritation and may protect against dryness and roughness.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [Acta Dermato-venereologica, 1999](https://pubmed.ncbi.nlm.nih.gov/10598752/)

### Where does it go in a skincare routine for sensitive skin?

This treatment goes in the evening routine. Sensitive skin needs a product of this type to start just once a week, using soothing ingredients and gentle exfoliants that keep the skin calm and smooth.

### Can I use this exfoliant with retinol, and in what order?

It is best to avoid using this exfoliant on the same night as retinol to keep your sensitive skin calm and prevent irritation. When using both in your routine, alternate the nights you apply them and always follow with a good moisturizer.

### How often should I use it?

Start using this treatment once a week in the evening, and if your skin tolerates it well and you see good results, you can carefully use it more often. This type of product needs soothing and calming ingredients to keep sensitive skin comfortable.

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

This exfoliant is unlikely to clog pores or cause breakouts for your sensitive skin, though it may occasionally lead to a slight tingling sensation or mild dryness. To better care for sensitive skin, an exfoliant of this type needs soothing ingredients like glycerin and plant extracts to keep skin calm and balanced while it renews.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
