Description
Junfeng Qi and four co-authors compared two lasers for sunken acne scars in a split-face trial, in a 2026 study. Each patient's face got one laser type on each side. Three sessions ran four weeks apart. Twenty-seven patients were followed for three months after the last session.
Both lasers improved scar scores by clear margins. Patient ratings of improvement also rose for both sides. No clear gap in effectiveness appeared between the two lasers. Patients were more satisfied with the ultra-short pulse laser side. That side also healed more kindly, with shorter redness and swelling. No crusting occurred on that side. The authors conclude both options work well and are safe. The pulse laser offered better comfort during recovery.
