  Lasers in Medical Science, 2025

• 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.

• 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

• A skin barrier restoring cream with shea butter, silkflo, and vitamin E increased type I procollagen synthesis, enhanced antioxidant enzyme activity, decreased reactive oxygen species generation, and promoted hyaluronic acid production in H2O2-stimulated human keratinocyte cells compared to untreated cells.

  International Journal of Cosmetic Science, 2025

• 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.

  BMC Oral Health, 2019

• Topical application of an antioxidant serum containing 15% ascorbic acid, 0.5% ferulic acid, and 1% tocopherol prevented particulate matter-induced degradation of extracellular matrix components, inflammation, and oxidative stress in the skin of 15 female volunteers compared to untreated controls.

  Journal of Cosmetic Dermatology, 2025

• Dermatological products containing d-alpha tocopheryl acetate showed non-comedogenic potential with less than a 50% increase in microcomedones in 12 healthy male subjects compared to octyl palmitate.

  Contemporary Clinical Trials Communications, 2021

• Topical application of an antioxidant mix containing 15% ascorbic acid, 0.5% ferulic acid, and 1% tocopherol prevented PM and UV-induced skin barrier perturbation, lipid peroxidation, inflammatory markers, MMP9 activation, and Type I collagen loss in 15 healthy females compared to untreated exposed skin.

  Journal of Cosmetic Dermatology, 2024

• Topical application of 5% vitamin C cream significantly improved global clinical scores, increased skin microrelief density, and induced elastic tissue repair in photoaged skin compared to excipient control in healthy female volunteers.

Why other moisturizers fit acne-prone skin better

• 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.
