Mapping the Research of Plasma in Dermatology by Bibliometric Approach

Background Plasma applications can lead to effective therapy for numerous skin diseases. We aim to systematically review the available data and map the plasma medicine in dermatology. Methods Publications relevant to plasma medicine in dermatology, published from 1996 to 2024, were retrieved from the Science Citation Index‐Expanded of the Web of Science Core Collection. Visual maps were conducted regarding annual production, collaborating countries or institutions, productive authors, core journals, co‐cited references, and keyword bursts. Results 460 articles were identified, and the number of publications has increased rapidly since 2008. Germany was the most influential country. Leibniz Institute for Plasma Science and Technology was the most productive institution. Weltmann, K. D. was the most prolific author. Wound healing, air plasma, dielectric barrier discharge, cold atmospheric plasma (CAP), antimicrobial, antifungal, argon plasma, plasma physical parameters, nitric oxide, and transdermal drug delivery were the top 10 clusters in the cocitation cluster analysis. Keyword burst analysis suggests that current research hotspots include CAP, nonthermal plasma, expression, and apoptosis. Conclusion This study provides an overview of plasma sources and their applications in dermatology. Plasma mechanisms and effects are currently hot topics. Most plasma applications focus on wound healing, infectious skin diseases, immune‐mediated skin diseases, and skin cancer. The parameter settings and treatment protocols of plasma for various skin diseases require further exploration. The present study maps the research landscape of CAP in dermatology and identifies directions for future investigation.
