Evaluation of the safety and efficacy of the thulium 1927 laser in aesthetic health: an integrative review.

Advances in aesthetics and dermatology bring alternatives for the treatment of pigmentary dysfunctions and photoaging. The thulium laser combines characteristics of ablative and non-ablative lasers, standing out for its high precision in epidermal penetration, promoting cell renewal, pigment removal and stimulation of collagen production, with good tolerability. 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. The studies carried out showed its efficacy in conditions such as melasma, scars and skin rejuvenation, with low adverse effects and high patient satisfaction. Although comparisons with other technologies, such as Er:YAG and Alexandrite lasers indicate some differences in results, the thulium laser offers advantages such as shorter recovery time and lower incidence of adverse effects. However, methodological and sampling limitations suggest the need for more robust clinical trials to consolidate their results and applications. It is concluded that the 1927 nm thulium laser represents a promising tool in aesthetic health, offering effective and safe treatment.
