## 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/))
- A topical gel containing chitosan, chlorhexidine, allantoin, and dexpanthenol significantly reduced postoperative pain, trismus, swelling, and analgesic consumption, while improving wound healing after third molar surgery compared to a placebo. ([Medicina Oral, Patologia Oral Y Cirugia Bucal, 2020](https://pubmed.ncbi.nlm.nih.gov/32683390/))
- Topical gel containing chitosan, 0.2% chlorhexidine, allantoin and dexpanthenol did not improve postoperative comfort regarding swelling and pain, but improved the wound's aesthetic appearance following impacted lower third molar extraction compared to no gel. ([Medicina Oral, Patologia Oral Y Cirugia Bucal, 2016](https://pubmed.ncbi.nlm.nih.gov/27475700/))
- 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/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction. ([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.
