June 2017 in “Journal of Pharmaceutical Sciences” This study found that coating liquid crystalline nanoparticles with chitosan significantly enhanced the skin permeation of 5α-reductase inhibitors, suggesting a promising strategy for improving topical delivery in androgenetic alopecia treatment.
January 2018 in “Refubium (Universitätsbibliothek der Freien Universität Berlin)” This study found that dexamethasone-loaded polymeric nanoparticles, particularly those combining ethyl cellulose with Eudragit® RS, may improve controlled release and penetration of corticosteroids into the skin and hair follicles compared to traditional methods.
