  The British Journal of Dermatology, 2010

• A novel triple-active cosmetic formulation containing 4-hexylresorcinol, retinyl propionate, and niacinamide improved the visual appearance of photoageing similarly to 0.02% tretinoin and reversed a consensus gene signature associated with ageing in female adults while causing less skin irritation.

  International Journal of Cosmetic Science, 2024

• 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, 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.
