TLDR Confocal Raman microscopy can effectively study drug delivery in hair follicles using pig ear models.
The study utilized confocal Raman microscopy to compare the chemical composition of human and porcine hair follicles, confirming optical similarity between the two species. This technique, combined with optical profilometry, provided a novel method for analyzing follicular penetration and component distribution in three dimensions. The research demonstrated that confocal Raman microscopy had significant potential as a noninvasive and chemically selective method for studying trans-follicular drug delivery, with excised pig ear serving as a reliable in vitro model for evaluating drug penetration into hair follicles.
