Background A variety of modalities have been used and, depending on the scar type, treatment may be invasive and/or conservative. Objective The aim of this study is to assess the safety and efficacy of treating stable nonhypertrophic scars using a fractional carbon dioxide (CO 2 ) laser. Patients and methods This is a prospective study of 25 patients (skin types III-IV, aged 6-37 years) with stable nonhypertrophic scars who underwent at least three sessions with a fractional CO 2 laser at 1-month interval. Side effects as well as improvements in texture, atrophy, and overall satisfaction with appearance were graded on a quartile scale by the patients and investigators after each treatment and 4 weeks after the final treatment. Before-after scores were compared using the Student t-test, with significance assigned to P values less than 0.05. Results All patients showed clinical improvement. There was no significant difference between the assessment of the investigator and the two blinded dermatologists. In terms of patient satisfaction, 32% of patients were not satisfied to slightly satisfied, whereas 68% were satisfied and 20% were very satisfied to extremely satisfied. Side effects were minimal and transient. Conclusion Fractional CO 2 laser treatment represents a safe, well-tolerated, effective, and promising treatment modality for nonhypertrophic traumatic and postinflammatory scars, with minimal downtime and fewer side effects.
