Abstract

Abstract: Background: Pinpoint irradiation technique CO2 LASER and Chemical Reconstruction Of Skin Scars (CROSS) are effective treatments for atrophic acne scars as fractional photothermolysis. Objective: This study was designed to prospectively compare the use of a pinpoint irradiation technique versus TCA CROSS in treating ice pick acne scars. Methods: Thirty-two patients with ice pick acne scars were included in this open, label pilot study. Pinpoint irradiation technique by CO2 LASER and TCA CROSS were applied for the study and control group, respectively. Twenty-eight patients with ice pick acne scars were included in this open, label pilot study. They were randomly assigned to two groups: the first group (14 patients) received pinpoint irradiation by CO2 LASER as a study group, and the second group (14 patients) received TCA CROSS as a control group. In both treatments, there were four sessions at 3-week interval, and 3 months of follow up. Results: There were statistically significant difference in acne scar severity index and qualitative scarring grading system in the improvement results between the study and control groups ( p < 0.05). Conclusion: Pinpoint irradiation technique by CO2 LASER is safe and more effective than TCA CROSS technique. Clinical improvement was achieved in all 14 patients without dramatic adverse effects.
