Abstract

Objectives: To evaluate the clinical efficacy of fractional Nd:YAG 1064nm picosecond laser in the treatment of atrophic scars in University Medical Center at Ho Chi Minh city. Material and methods: A descriptive study of a series of cases, longitudinal follow-up was conducted on 26 patients with atrophic scar and indicated treatment with fractional Nd:YAG 1064nm picosecond laser at Department of Dermatology and Skin Aesthetics – University Medical Center at Ho Chi Minh city from 8/2021 to 8/2023. Results: Among 26 patients in this research, the mean age was 30,9, most of them had Fitzpatrick skin type IV, history of comedo extraction and had family history of atrophic scar. Stratification of patients regarding severity led to 11% in the mild subgroup, 19% in the moderate subgroup, and 70% in the severe subgroup. After 3 treatments with fractional Nd:YAG 1064nm picosecond laser, 96,9% of patients reported satisfied or very satisfied with the results. Goodman-Baron score improved, but the difference after first and second treatment did not reach statistical significance until the third time (p < 0,001). Skin analysis score using VISIA and Colorimeter also showed significant improvements. The amelioration of Goodman & Baron in the subgroup treated with high laser energy was significantly better than the low and moderate subgroup. Conclusion: Fractional Nd:YAG 1064nm picosecond laser is an effective and promising method in the treatment of atrophic scars.
