Abstract：Objective: To compare the clinical removal efficacy and adverse reaction incidence of picosecond laser with different energy parameters in tattoo treatment, so as to select safe and efficient clinical treatment parameters.Methods: A retrospective study was conducted on 66 patients with tattoos who received picosecond laser treatment in our hospital from January 2024 to December 2025. According to different laser energy parameters, the patients were divided into low-energy group（21 cases）, medium-energy group (23 cases) and high-energy group（22 cases）. All patients were treated with picosecond laser with consistent wavelength, pulse width and treatment course, with only energy parameters adjusted. The total effective rate of tattoo removal, number of treatment sessions, and incidence of adverse reactions（pigmentation and blisters）were compared among the three groups. Results: The high-energy group had the highest total effective rate of tattoo removal, followed by the medium-energy group, and the low-energy group was the lowest, with statistically significant differences among groups（P<0.05）. The curative effect was mainly dominated by excellent and effective cases, with a low proportion of cured cases. The medium-energy group had the least average treatment times, while the low-energygroup had the most（P<0.05）. Only pigmentation and minor blisters were counted as adverse reactions, and the high-energy group had a significantly higher adverse reaction rate than the medium and low-energy groups（P<0.05）. Conclusion: The efficacy of picosecond laser for tattoo removal is positively correlated with laser energy parameters. High-energy parameters achieve the best removal effect but bring significantly higher risk of skin adverse reactions. Medium-energy parameters balance efficacy and safety with fewer treatment times and controllable complications, which is more suitable for clinical promotion in routine tattoo treatment.
