Evaluation of 755-nm Picosecond Alexandrite Laser With a Focus Lens Array for the Treatment of Enlarged Facial Pores

Objectives: This study aims to evaluate the use of 755-nm picosecond alexandrite laser with a focus lens array to treat facial pores. Methods: Laser treatment was performed on 129 patients between January 2021 and October 2022. VISIA imaging system was used for photographic assessments, the total average number and pore index was calculated, the physicians’ assessment score and patient satisfaction score were collected, and the incidence of disadvantage effects was also documented. Results: The mean patient age was 35.2±6.4 years (21–45 y). The total average number of facial pores was 1614.1±412.8, and the total average number decreased to 1262.6±356.2 three months after the last treatment. The pretreatment baseline of pore index was 26.1±4.5, while the pore index was 21.3±3.7 three months after the last treatment. The physicians’ assessment score was 2.7 on the 0-to-4 scale, and patient satisfaction score was 3.5 on the 1-to-5 scale. There were no adverse events, such as hyperkeratosis, scarring, and hypo-or hyperpigmentation. Conclusions: 755-nm picosecond alexandrite laser with a focus lens array was safe and effective in the treatment of facial pores with relatively few unanticipated adverse events. Level of Evidence: Level IV—observational study without controls.
