Subcision with Blunt Cannula in Combination with Injection of PRP and Microneedling in Treatment of Acne Scars

This study evaluated the effectiveness of combining subcision with blunt cannula, platelet-rich plasma (PRP) injection, and microneedling in treating post-acne rolling scars. Conducted on 50 patients with mild to severe rolling acne scars, the trial found that the combination of subcision, derma pen, and plasma significantly increased the improvement of ordinary acne and scar types compared to other treatment groups. The study concluded that PRP and radiofrequency microneedling were effective in treating atrophic acne scars in over 80% of patients, with minimal adverse effects. There were no significant differences in patient satisfaction or previous scar types among the treatment groups.
