## 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/))
- Topical application of 1,3-propanediol at various concentrations, alone or combined with butylene glycol and/or glycerol, increased skin hydration and reduced trans epidermal water loss in 30 healthy female subjects over an 8-hour period, with the 15% concentration and the addition of glycerol providing greater benefits. ([International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/))
- Emulsions containing ceramides 1 and 3 improved skin hydration and reduced transepidermal water loss in sodium lauryl sulfate-irritated skin of fifteen healthy Asian women compared to a control emulsion. ([International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- 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.

- Treatment with 2-mercaptonicotinoyl glycine (2-MNG) significantly reduced immediate darkening and inhibited new melanin production in subjects with melanin-rich skin compared to vehicle controls. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38372022/))
- 2-mercaptonicotinoyl glycine 0.5% ranked first with a high probability of immediate and persistent efficacy against UV daylight-induced pigmentation compared with 13 other reference molecules in women with skin phototype III. ([Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38433524/))
- Topical 2-mercaptonicotinoyl glycine (0.5% or 1%) significantly decreased high energy visible light-induced pigmentation compared to vehicle in 58 individuals with Fitzpatrick Phototype III or IV, whereas ascorbic acid 7% showed no efficacy.
