## 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.

- 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/))

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

Glycolic acid makes this exfoliant a good fit for mature skin by helping smooth wrinkles and fine lines, while glycerin supports skin health by providing essential hydration. An exfoliant for mature skin needs exceptionally safe formulas, high concentrations of potent antioxidants, and hydrating ingredients that target fine lines and wrinkles while keeping the skin calm.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Glycolic acid helps smooth mature skin by encouraging fresh skin renewal and supporting firmness. It may also help improve signs of photoaging and increase moisture levels over time.
Sources: [Dermatologic Surgery, 1998](https://pubmed.ncbi.nlm.nih.gov/9793513/), [Acta Medica, 2016](https://pubmed.ncbi.nlm.nih.gov/27131351/)

### What does Glycerin do for mature skin?

Glycerin helps keep mature skin feeling soft and smooth by drawing moisture into the outer layer and locking it in. This daily hydration boost supports the skin barrier, keeping dry areas comfortable and protected against 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 this exfoliant go in a skincare routine for mature skin?

This exfoliant treatment goes in the evening routine after cleansing and before moisturizing. To better fit mature skin, this type of product needs ingredients that provide deep hydration and antioxidants alongside gentle exfoliating acids.

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

It is best to use this exfoliant on separate nights from your retinol to help prevent dry or irritated skin. Using strong exfoliating acids and retinol together can easily overwhelm mature skin, so mature skin of this type needs gentle hydrating ingredients and soothing plant extracts to stay calm and smooth.

### How often should I use this exfoliant?

Start using this exfoliant once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. This approach helps smooth fine lines while keeping your skin calm.

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

This exfoliant is unlikely to clog pores or cause breakouts for mature skin since it has a safe profile and lacks harsh ingredients. However, it may cause mild dryness or a slight tingling sensation. Mature skin typically needs a product with gentle exfoliating acids combined with rich hydrators like glycerin and antioxidants to support skin renewal while keeping the face smooth and soft.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Yes, it has no fragrance and no drying alcohol.
