December 2024 in “Pharmaceutics” This review examines hydrogel microneedles for transdermal drug delivery, discussing their applications and challenges but reports no new clinical results.
May 2026 in “Journal of Nanobiotechnology” This study found that using a palmitoylated peptide, Pal-MPAPO, delivered through hydrogel microneedles effectively promoted hair regrowth in mice with efficacy comparable to minoxidil, while requiring less frequent application.
September 2026 in “Advanced Materials Technologies” In a mouse model study, researchers developed a methacrylated hyaluronic acid-based hydrogel microneedle patch co-loaded with finasteride and a carbon monoxide-releasing molecule for androgenetic alopecia, which showed better hair regrowth and safety compared to traditional treatments, offering an innovative approach with minimized systemic side effects.
March 2026 in “Journal of Nanobiotechnology” This study developed a hydrogel microneedle system combining ginseng-derived exosomes and biomimetic nanoparticles to address oxidative stress, inflammation, and melanocyte deficiency in vitiligo, showing significant repigmentation in mice within 3 weeks by enhancing melanocyte protection and keratinocyte proliferation.
