- 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/))
- 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 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.
