ABSTRACT
OBJECTIVES:
There have been few studies regarding the use of a picosecond-domain laser for acne scars in Asians. This prospective study evaluated the efficacy and safety of a high-energy 1,064 nm NdYAG picosecond-domain laser for ablation and resurfacing of facial acne scars in Asians.METHODS:
Subjects were treated with a 1,064 nm picosecond laser (8 mm spot, 0.7-1.0 J/cm2 , 5 Hz) every 4 weeks for three sessions. Two blinded dermatologists evaluated the pre- and 3-month post-treatment images with a 10-point improvement scale. Subject pain, global improvement, and satisfaction were also assessed. The Facial Acne Scar Quality of Life (FASQoL) questionnaire was used to evaluate the subjects' quality of life.RESULTS:
Twenty subjects aged 18-50 years with Fitzpatrick skin type III-V were enrolled. The median dermatologist-rated improvement score was 3 out of 10. Subjects were satisfied to very satisfied with global improvement. Subjects' quality of life significantly improved with a median FASQoL score of 10 after treatment compared with 21 before treatment (P < 0.001). Adverse effects were limited to erythema, pain, and edema without postinflammatory hyperpigmentation.CONCLUSIONS:
The 1,064 nm picosecond-domain laser with ablative resurfacing parameters is safe and effective for the treatment of acne scars in Asians. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.Palavras-chave
