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

• 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

• Quercetin loaded composite nanofibers achieved a skin deposition of 28.24%, higher antibacterial efficacy against Propionibacterium acne compared to quercetin alone, safety on skin fibroblastic cells, and a reduction of 61.2% in inflammatory, 14.7% in comedonal, and 52.9% in total acne lesions in acne patients.

  International Journal of Pharmaceutics, 2022

• Quercetin exhibits pronounced antioxidant and antiinflammatory activities for skin supplementation, though its poor solubility limits dermal penetration.

  European Journal of Pharmaceutics and Biopharmaceutics, 2016

• Quercetin phospholipids 1% cream significantly reduced UV-, histamine-, and chemical-induced skin erythema (-10.05%) and mean wheal diameter in 30 healthy human volunteers, showing comparable efficacy to 1% dexchlorpheniramine cream.

  Clinical, Cosmetic and Investigational Dermatology, 2016

• Quercetin-loaded niosomes formulated with Span60-RH40 at a 9:11 mass ratio improved quercetin solubility, photostability, sustained release, and transdermal penetration, yielding a skin retention 2.95 times higher than quercetin solution.

  Molecules, 2019

• Optimized rutin-loaded glycerosomes formulated into a nanosunscreen gel demonstrated sustained drug release, greater skin permeation, good antioxidant activity, and better epidermal retention compared to the dermis, indicating high safety, stability, and sun protection factor values for topical administration.

  Gels, 2023

• 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

• 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

• 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.
