What the research says

• A multi-modal methodology combining MALDI-MSI, in vivo RCM, echography, and histology revealed age-related decreases in extracellular matrix and epidermal-dermal junction proteins and undulation depth, while a blend of palmitoyl oligopeptide and palmitoyl tetrapeptide-7 improved subepidermal low-echogenic band thickness, density, and extracellular matrix structure compared to placebo.

  Journal of Cosmetic Dermatology, 2015

• Palmitoyl tetrapeptide-7, acetyl hexapeptide-8, palmitoyl tripeptide-1, and palmitoyl tetrapeptide-10 significantly increased type III collagen levels in human dermal fibroblasts following UV exposure, with their combination demonstrating a greater effect in vitro and enhancing type I, III, and IV collagen levels in ex vivo skin tissues compared to individual components.

  International Journal of Cosmetic Science, 2026

• 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

• A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers.

  Journal of Cosmetic Dermatology, 2020

• 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.

  Experimental Dermatology, 2003

• Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation.

  Journal of Periodontology, 2009

• Topical application of VC-IP cream twice daily for 8 weeks reduces periorbital wrinkles in female subjects compared to a placebo cream.

  Journal of Cosmetic Dermatology, 2022

• 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.

  Military Medicine, 2024

• A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate.

  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.
