research Enhanced therapeutic effects of all-trans retinoic acid nanostructured lipid carrier composite gel drug delivery system for alopecia areata
This study reported that an ATRA-loaded nanostructured lipid carrier gel (ATRA-NLC-Gel) improved symptoms of alopecia areata in mice by enhancing transdermal drug delivery, reducing skin irritation, and promoting hair regrowth through targeted follicle enrichment and pathway activation.
