- 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.

([Journal of Cutaneous and Aesthetic Surgery, 2019](https://pubmed.ncbi.nlm.nih.gov/31619887/))
- Commonly used chemical peels showed no significant differences in effectiveness for acne vulgaris in most comparisons, though combined salicylic and mandelic acid peeling was superior to glycolic acid and glycolic acid was superior to placebo, based on twelve randomized controlled trials.
