## What the research says

- 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 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/))

([Skin Pharmacology and Physiology, 2018](https://pubmed.ncbi.nlm.nih.gov/29131088/))
- Liposomal encapsulation of octyl methoxycinnamate increases its safety, skin affinity, and in vivo solar photoprotection factor while slowing its release and enhancing retention in the stratum corneum compared to a conventional formulation. ([International Journal of Nanomedicine, 2013](https://pubmed.ncbi.nlm.nih.gov/24376350/))
- Encapsulation of ethylhexyl methoxycinnamate and butyl methoxydibenzoylmethane in lipid microparticles significantly reduced their in vivo human skin penetration compared to nonencapsulated filters. ([Skin Pharmacology and Physiology, 2011](https://pubmed.ncbi.nlm.nih.gov/21336009/))
