Questions and answers

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

• A lipid mixture enriched by ceramide NP with fatty acids of diverse chain lengths significantly improved skin barrier recovery rate, stratum corneum integrity, and hydration compared to a vehicle cream in healthy adult male volunteers with corticosteroid-impaired skin.

  Skin Pharmacology and Physiology, 2022

• Soaps containing betaine caused the least skin irritation compared to other tested soaps in twenty-eight healthy subjects, though irritation did not decrease with increasing concentrations of betaine.

  Skin Research and Technology, 2003

• A combination of Aloe barbadensis leaf extract and trimethylglycine in a 1:1 mass ratio synergistically increased aquaporin 3 expression by up to 380% in keratinocytes and safely improved skin hydration in healthy volunteers.

  Molecules, 2024

• 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

• 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

• 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.

  BMC Oral Health, 2019

• 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

• 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

• 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

• Topical dry mouth products containing olive oil, betaine, and xylitol significantly increased unstimulated whole salivary flow rates, reduced xerostomia complaints, and improved quality of life in adults with polypharmacy-induced xerostomia compared to their normal routine care, with no clinically significant adverse events.

  Journal of Oral Rehabilitation, 2007

• Mixed surfactant systems of sodium dodecyl sulfate and dimethyl dodecyl amido betaine significantly reduce acute skin irritation potential in human volunteers compared with the individual surfactants, demonstrating that irritation potential cannot be predicted by simple summation.

  Food and Chemical Toxicology, 1998

• Polyhexanide/betaine may be nontoxic and effective in enhancing wound healing, whereas the majority of other topical cleaning agents are locally toxic and of limited or no proven efficacy.

  Advances in Skin & Wound Care, 2013

Why other moisturizers fit acne-prone skin better

• A peel-off facial mask containing myoinositol and trehalose-loaded liposomes improved adult female acne by decreasing lesion counts, sebum production, GAGS scores, and local androgen levels while increasing beclin-1 levels.
