This study conducted an integrative review on the safety and efficacy of the 1927 nm fractional Thulium laser in the treatment of aesthetic dysfunctions. Searches were conducted in the databases MEDLINE/PubMed, Science Direct, Scopus, Google Scholar and Capes Journals between 2014 and 2024, to select studies that demonstrate the results of the application of this treatment.
