Clinical Efficacy and Safety of Pulsed Dye Laser Combined with Pingyangmycin on Hyperplastic Scar After Acne

The study evaluated the clinical efficacy and safety of pulsed dye laser (PDL) combined with pingyangmycin (PI) for treating hyperplastic scars (HS) after acne in 109 patients. The research group (n=52) showed a higher total effective rate, better scar repair, skin improvement, and granulation tissue maturity compared to the control group (n=57). Both groups had similar adverse reaction rates and recurrence rates. The research group also reported higher treatment comfort, satisfaction, psychological state, and quality of life. The study concludes that PDL combined with PI is effective and has a promising clinical application for treating HS.
