A total of 44 patients (18\u2013 55 years old), skin types III-V, with acne scars, were enrolled. Four sessions of MNRF (Lumenis legend PRO Machine, with non-insulated needle tips GEN6, GEN6L; Israel) were done with an interval of 3 weeks between each session and followed up 1 month after the last session. The outcome was assessed by Goodman and Baron\u2019s qualitative and quantitative acne scar grading, physician global assessment (PGA), and patient satisfaction score (PSS).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>Out of 44 patients, four patients could not complete the study.

At the end of follow-up, patients with Grades 1, 2, 4, and 4 acne scars were 5 (12.5%), 24 (60%), 10 (25%), and 1 (2.5%), respectively, which were statistically significant (<jats:italic>P<\/jats:italic> &lt; 0.05).

Goodman and Baron\u2019s quantitative assessment showed an initial mean of 12.65 and an after-follow-up mean of 8.3, which was statistically significant <jats:italic>(P<\/jats:italic> &lt; 0.05). PGA and PSS scores showed excellent to good responses of 70% and 82.5%, respectively. Adverse effects such as post-treatment erythema were seen in all patients, and edema was observed in 12 patients.
