## Why this fit

- Offers moderate exfoliation for pigmentation on your normal skin due to the presence of glycolic acid, which promotes skin renewal and has keratolytic action, complemented by glycerin's humectant properties.
- The inclusion of Lespedeza Capitata stem extract and flower leaf extract provides additional antioxidant benefits, supporting overall skin health.
- The product is safe for your normal skin, as it lacks prohibited or harsh ingredients and poses no 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/))
- 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/))
- 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 skin with dark spots?

Medik8 Sleep Glycolic works moderately well for dark spots on normal skin by helping renew the skin and target pigmentation. However, an exfoliant treatment for this skin needs a blend of effective antioxidants and soothing ingredients with no irritation risk, along with hydrating components and skin-repairing ingredients to deliver optimal results.

### Which ingredients make this exfoliant a good fit for skin with dark spots?

Glycolic acid makes this exfoliant a good fit for skin with dark spots by promoting skin renewal, while glycerin keeps your skin hydrated. An exfoliant of this type needs a blend of effective antioxidants and soothing ingredients that provide significant benefits for dark spots without any risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Glycolic Acid do for skin with dark spots?

Glycolic acid helps fade dark spots and improves uneven skin tone by encouraging the shedding of pigmented surface cells. When used in treatments or peels alongside other brightening ingredients, it may further reduce the severity of stubborn discoloration.
Sources: [The Journal of Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17204097/)

### What does Glycerin do for skin with dark spots?

Glycerin helps keep dry skin hydrated and supports a healthy skin barrier, which makes skin feel soft and smooth. While it does not directly fade dark spots on its own, it is often added to spot-fading products to keep the skin comfortable while other ingredients work.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Acta Dermato-venereologica, 2017](https://pubmed.ncbi.nlm.nih.gov/27349297/)

### Where does this exfoliant go in a skincare routine for skin with dark spots?

This exfoliant goes in the evening routine after cleansing and before moisturizing, starting once a week and using it more often only if your skin handles it well. To fade dark spots effectively, this skin type needs products with strong skin-brightening ingredients and targeted exfoliating acids that speed up skin renewal.

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

Using this exfoliant with retinol may easily cause irritation on your skin, so it is best to use them on alternate nights rather than together. To fade dark spots better, this skin needs targeted brightening ingredients and gentle renewing acids that work without overloading your routine.

### How often should I use this exfoliant?

Start using this exfoliant treatment once a week in the evening, and if your skin feels comfortable and you see good results, you may carefully use it more often. Dark spots on normal skin do best with glycolic acid for renewal paired with glycerin to keep skin soft.
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 this exfoliant clog pores, cause breakouts or purging for skin with dark spots?

This exfoliant is unlikely to clog pores or cause breakouts on your skin, as it lacks heavy or pore-clogging ingredients and poses very little risk of irritation. It helps fade dark spots by promoting skin renewal, but because it is an average fit for your skin, darker spots need a product with stronger brightening ingredients and antioxidants.

### Is this exfoliant fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
