## 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/))
- 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/))

- 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.

- 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/))
- A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate. ([Skin Research and Technology, 2000](https://pubmed.ncbi.nlm.nih.gov/11428946/))
- 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/))
- 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/))

## Questions and answers

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

Medik8 Sleep Glycolic works for your combination skin, though other products fit it better. It offers moderate exfoliation because glycolic acid helps to smooth texture and manage oily shine, while glycerin provides essential hydration to balance drier areas. A product for this skin needs effective ingredients like niacinamide, propolis, or zinc PCA that regulate oiliness, enhance radiance, and provide optimal hydration without any risk of irritation.

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

Glycolic acid helps to smooth texture and manage oily shine, while glycerin provides essential hydration to balance drier areas. To fit combination skin even better, this type of product needs ingredients like niacinamide, propolis, and zinc PCA to regulate oiliness and enhance radiance without irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Glycolic acid helps smooth and brighten combination skin by gently loosening dead surface cells to speed up skin renewal. This ingredient is unlikely to cause irritation when used properly, but it needs a reliable sunscreen during the day since it makes skin more sensitive to the sun.
Sources: [Acta Dermato-venereologica, 1995](https://pubmed.ncbi.nlm.nih.gov/8651024/), [Archives of Dermatological Research, 1997](https://pubmed.ncbi.nlm.nih.gov/9248619/)

### What does Glycerin do for combination skin?

Glycerin helps keep combination skin soft and smooth by pulling moisture in and keeping it there. It improves hydration and supports your skin barrier, which is unlikely to cause irritation.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This treatment goes in your evening routine, starting at once a week before moisturizing. Combination skin needs glycolic acid to resurface texture and manage oily shine alongside glycerin for essential hydration in drier areas.

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

It is best not to use this exfoliant in the same routine as retinol, as combining them may easily cause dryness or irritation on your combination skin. Instead, alternate the nights you use them or use retinol on different days to keep your skin smooth and calm.

### How often should I use it?

Start by using this treatment once a week in the evening, and if your skin handles it well and shows good results, you may carefully use it more often. This approach helps you manage oily shine while avoiding irritation on drier areas of your combination skin. A product of this type needs a balance of exfoliating ingredients like glycolic acid alongside hydrating ingredients like glycerin to properly care for combination skin.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32356917/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38406974/)

### Can Medik8 Sleep Glycolic clog pores, cause breakouts or purging for combination skin?

Medik8 Sleep Glycolic is unlikely to clog pores or cause breakouts on combination skin, as it helps resurface texture and manage oily shine. Combination skin needs ingredients like glycolic acid to clear dead cells and glycerin to hydrate drier areas without heaviness.
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.
