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.
