April 2023 in “ACS Biomaterials Science & Engineering” This study explored the potential of silk fibroin methacrylate hydrogel microneedles to deliver α-MSH directly to the epidermis in vitiligo patients, enhancing melanocyte protection and melanosome transfer, potentially offering a new treatment avenue for this challenging condition.
June 2026 in “ACS Applied Nano Materials” This study developed and tested a novel microneedle treatment loaded with nanoparticles for vitiligo, leading to enhanced skin repigmentation by targeting immune cells and reducing oxidative stress in a minimally invasive manner.
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.
January 2023 in “International journal of dermatology, venereology and leprosy sciences” This study suggests that microneedling may be an effective and less painful treatment for vitiligo, offering benefits over traditional needle injections, particularly in challenging-to-treat areas like the extremities or stubborn regions.
