## What the research says

- 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](https://pubmed.ncbi.nlm.nih.gov/20374604/))
- 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](https://pubmed.ncbi.nlm.nih.gov/38685700/))
- Topical palmitoyl pentapeptide (pal-KTTKS) provided significant improvement versus placebo control in the reduction of wrinkles and fine lines in Caucasian female subjects. ([International Journal of Cosmetic Science, 2005](https://pubmed.ncbi.nlm.nih.gov/18492182/))
- Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle. ([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- 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](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Silicone particles encapsulating retinol increased its half-life by 9-fold and yielded 12-23% lower skin irritation in human subjects compared to Microsponge particles while maintaining biological activity. ([Journal of Controlled Release, 2018](https://pubmed.ncbi.nlm.nih.gov/29604311/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- 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](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- 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](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- 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. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- 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](https://pubmed.ncbi.nlm.nih.gov/34980969/))
- Topical retinyl propionate cream produced no statistically significant differences compared to placebo for any clinical, histological, or profilometric parameters of skin photoageing in 80 subjects. ([Clinical and Experimental Dermatology, 1998](https://pubmed.ncbi.nlm.nih.gov/9894360/))
- 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.
