Background: Q-Switched Nd:YAG laser (1064 nm) is a new modality that was reported to be effective in treatment of acne scars.
Objective: To evaluate the effectiveness and the safety of this laser in treatment of acne scars.
Patients and methods: This case series, descriptive and comparative study was conducted in Al-Najaf Teaching Hospital of Kufa Medical College, Iraq from October 2010 to October 2011. A total of 16 patients having mild to moderate facial acne scars were enrolled; 10 of them completed the study. All patients had Fitzpatrick skin type III. They were divided into two groups A and B and were treated with two different energy fluences: 5 J/cm2 for group (A) and 15 J/cm2 for group (B). Five treatment sessions with 2-week intervals were done for all patients and were followed up for 6 months. The improvement was evaluated by objective and subjective methods.
Results: Changes in acne scores in both groups were statistically insignificant after 6 months follow-up. Only two patients were satisfied with the improvement after treatment- one patient from each group. No serious side effects were reported.
Conclusion: Q-Switched Nd:YAG laser (1064 nm) can be used in treating atrophic facial scars of acne vulgaris.
