  American Journal of Clinical Dermatology, 2002

• A new topical panthenol-containing emollient significantly improved transepidermal water loss reduction, stratum corneum hydration, and intercellular lipid lamellae length compared with control in healthy subjects without negatively impacting bacterial viability.

  The Journal of Dermatological Treatment, 2017

• A panthenol-enriched mask significantly decreased erythema and hyperpigmentation, increased sebum and stratum corneum moisture, and reduced transepidermal water loss compared to a saline dressing in 60 subjects undergoing facial laser treatment.

  Journal of Cosmetic Dermatology, 2025

• 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

• A vitamin A palmitate and antioxidant-containing oil-based moisturizer improved fine lines, wrinkles, pigmentation, tone, texture, dryness, firmness, and clarity across various body sites compared to a no-treatment group over 12 weeks.

  Journal of Cosmetic Dermatology, 2013

• 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

• Topical formulation containing hesperidin methyl chalcone inhibited skin oxidative stress, inflammation, and cytokine production induced by ultraviolet B irradiation in hairless mice.

  Photochemical & Photobiological Sciences, 2016

• 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

• 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

Why other eye cares fit skin with dark spots better

• An antipollution, antioxidant serum containing Deschampsia antarctica extract, ferulic acid, and vitamin C reduced transepidermal water loss by 19%, improved dark spots by 7%, and decreased the squalene peroxide to squalene ratio by 16% compared to baseline in twenty women living in a high air pollution area over 28 days.

  Clinical, Cosmetic and Investigational Dermatology, 2019

• Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging.

  The British Journal of Dermatology, 2019

• Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.
