Acne scar treatment using high-energy fractional nanosecond Q-switched 1064 nm laser

Abstract

Aims: The objective of this study was to evaluate the effectiveness and safety of high-energy ablative fractional nanosecond Q-switched 1064 nm laser therapy for acne scars. Material and methods: Forty-six patients aged from 16 to 69 years and of Fitzpatrick skin type from 2 to 4 were included in this retrospective study. Multiple passes were delivered with a fractional 1064-nm handpiece at high energy. Results were evaluated using blinded analysis of patient before and after photographs and also by evaluating patient satisfaction. Results: Most patients (75%) were improved or very improved according to blinded evaluation. Patient satisfaction was high. No hypo/hyperpigmentation, scarring, or any other side effects were reported by any of the patients. Conclusions: The study demonstrated good clinical outcomes in facial acne scar management with a high patient satisfaction rate and no adverse side effects.
