Successful treatment of depressed facial scars using single monopolar microneedle radiofrequency: case reports

The increasing demand for scar treatments has led to various innovative methods.This paper presents two cases involving the treatment of distinct scar types using a single monopolar microneedle radiofrequency (SMNR) device.The first case involved a 52-year-old male with 2-cm linear depressed facial scar of unknown etiology.The patient underwent two sessions of SMNR spaced two weeks apart and showed scar improvement after four weeks.The second case involved a 35-year-old male presenting with a combination of icepick and boxcar acne scars on both cheeks.He received seven SMNR treatments every two weeks and showed scar improvement after 12 weeks.In both cases, scar improvement was achieved through subcisions of fibrous septa combined with dermal remodeling using microneedle radiofrequency.This case report shows that SMNR is an effective and safe modality for treating various types of scars, including acne scars, with minimal downtime and no significant adverse effects.
