Background：The management of acne scars poses a significant challenge for dermatologists.With the development of laser technology, its clinical application in the field of acne scar is increasing year by year.However, there is a lack of bibliometric analysis on the laser treatment of acne scars. The objective of this study is to utilize bibliometrics to gain a comprehensive understanding of the development trends and research hotspots in the field of laser treatment for acne scars.
Method：With "acne scar*" and "laser" as the themes, the publications about laser treatment of acne scar from 2014 to 2023 were searched in the WoSCC database. The literatures were visualized by VOSviewers, CiteSpace and R software packages, and the maps of countries, research institutions, authors, journals, references and keywords were drawn
Results: A total of 430 articles from 46 countries were included in the analysis, with the United States and China taking the lead. The main research institutions are Mahiron University in Thailand, Cairo University in Egypt and Chulalongkorn University in Thailand. "Journal of Cosmetic Dermatology" became the journal with the largest number of articles in this field, and "Dermatologic Surgery" became the most cited publication.A total of 1695 authors contributed to these publications, with Manuskiatti Woraphong being the most prolific contributors. Notably, Alster Tina received the highest co-citations. Research on the effectiveness of lasers in treating acne scars is a significant area of focus in this field. Among the various types of lasers, CO2 lasers are the most commonly utilized.Emerging research hotspots include various types of lasers, as well as microneedle radiofrequency and combination therapy
Conclusion: Treatment effectiveness is the focus of research in this field. Combination therapies such as laser, microneedle combined with platelet-rich plasma, hyaluronic acid and new picosecond lasers have gradually become a hot topic in this research field and trend
