Study on Oil-in-Water Nanoemulsion-Based Local Transdermal Delivery System

This study from Kyushu University explores the development of an oil-in-water nanoemulsion (O/W-NE) system for enhanced transdermal delivery of hydrophobic drugs. The nanoemulsion, with an average droplet size of ~100 nm, incorporates glycerin to improve penetration and stability, demonstrating high drug encapsulation efficiency and reduced burst release. The system was tested in models for skin barrier repair and androgenetic alopecia (AGA), showing effective skin repair and follicular targeting. The O/W-NE platform offers a promising strategy for treating skin diseases and developing animal models, with potential applications in epidermal therapy and regenerative medicine.
