• Over-the-counter retinol products provided only weak evidence for a mild ameliorating effect on fine facial skin wrinkle lines in randomized, double-blind, vehicle-controlled trials, and major methodological flaws call the validity of positive results into question.

  The Journal of Clinical and Aesthetic Dermatology, 2021

• A cosmetic niacinamide/peptide/retinyl propionate regimen significantly improved periorbital wrinkle appearance relative to a 0.02% tretinoin regimen at 8 weeks with comparable benefits at 24 weeks, while demonstrating significantly better tolerability in 196 women.

  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

• Cosmetic products containing 4-t-butylcyclohexanol demonstrated a faster and more pronounced soothing effect on capsaicin-induced burning compared to those containing acetyl dipeptide-1 cetyl ester in volunteers with sensitive skin.

  Journal of the European Academy of Dermatology and Venereology, 2016

• Rice protein hydrolysate and its characteristic peptides Leu-Leu-Lys, Leu-Pro-Lys, and pyroGlu-Lys reduced melanin content, tyrosinase activity, and ROS production in UVB-induced human epidermal melanocyte PIG1 cells by regulating the JNK/Β-Trcp/NFΗB-p65/MITF signaling pathway and lowering TRP-1 and TRP-2 expression.

  Food & Function, 2020

• Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups.

  Skin Research and Technology, 2000

• Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms.
