## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Topical dexpanthenol acts as a moisturizer, improves stratum corneum hydration, accelerates wound healing and epidermal regeneration, reduces erythema, and improves symptoms of skin irritation compared to vehicle or no pretreatment. ([American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/))
- 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](https://pubmed.ncbi.nlm.nih.gov/27425824/))
- 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](https://pubmed.ncbi.nlm.nih.gov/40613435/))
- A topical formulation containing kojic acid, emblica extract, and glycolic acid demonstrated efficacy parity compared with hydroquinone 4% in multiethnic participants with mild to moderate facial dyschromia. ([Cutis, 2010](https://pubmed.ncbi.nlm.nih.gov/21049734/))
- A nanoemulsion containing 1 mg/mL kojic dipalmitate and 5% rosehip oil demonstrated high incorporation efficiency, suitable physicochemical stability, antioxidant and depigmenting efficacy close to 1 mM ascorbic acid, and no cytotoxicity at concentrations from 0.06% to 1% in vitro. ([Pharmaceutics, 2023](https://pubmed.ncbi.nlm.nih.gov/36839792/))
- Topical application of iron chelators kojic acid and deferiprone significantly accelerated wound healing in rats compared to control groups, with deferiprone showing superior efficacy due to higher antioxidant and iron chelation abilities. ([International Wound Journal, 2013](https://pubmed.ncbi.nlm.nih.gov/22621771/))
- 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.
