What the research says

• Cosmetic formulations containing 5% Centella asiatica extract showed the best efficacy in improving skin moisture and decreasing transepidermal water loss, while also exhibiting antiinflammatory properties in 25 volunteers compared to baseline measurements.

  Indian Journal of Pharmaceutical Sciences, 2016

• Co-delivery of paeonol and madecassoside via nanoemulsions improved transdermal delivery, promoted barrier repair proteins, inhibited inflammatory cytokine secretion in cellular and 3D models, and reduced transepidermal water loss and acne in human facial skin compared to free components.

  Molecules, 2023

• Topical application of an emollient emulsion containing 15.0% caprylic/capric triglyceride doubled the amount of urocanic acid isomers and increased skin hydration with reduced transepidermal water loss in healthy subjects, though it did not prevent ultraviolet-induced urocanic acid isomerization.

  Life, 2023

• 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

• Topical application of 0.05% w/w ECa 233 gel reduced erythema index by 0.03 U and improved early crusting and general wound appearance compared to placebo in thirty individuals undergoing facial laser resurfacing.

  Journal of Alternative and Complementary Medicine, 2020

• 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

• Moisturizer containing 5% panthenol, madecassoside, and copper-zinc-manganese decreased adverse reactions and downtime after ablative fractional carbon dioxide laser resurfacing with comparable efficacy to 0.02% triamcinolone acetonide cream in 20 subjects.

  Journal of Cosmetic Dermatology, 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 dexpanthenol acts as a moisturizer, improves stratum corneum hydration, accelerates wound healing and epidermal regeneration, reduces erythema, and improves symptoms of skin irritation compared to vehicle or no pretreatment.

  American Journal of Clinical Dermatology, 2002

• Topical dexpanthenol formulated in lipophilic vehicles improved stratum corneum hydration and reduced transepidermal water loss compared to vehicle control in humans.

  Arzneimittel-Forschung, 2000

• Hyaluronic acid, hyaluronic acid plus dexpanthenol, and isotonic saline nasal sprays all significantly improved dry nose symptoms over four weeks in 240 patients, with hyaluronic acid plus dexpanthenol providing superior nasal moisturisation compared to the other two.

  Auris, Nasus, Larynx, 2020

• 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

• 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

• 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.
