Comparing the efficacy of two minimally invasive treatments for linear scars: fractional microneedling radiofrequency and microneedling with platelet-rich plasma filler

Background Linear scars present esthetic issues for numerous people, particularly in visible regions. Recently, fractional microneedling radiofrequency (FRF) has been employed to address linear scars. Platelet-rich plasma injection and collagen induction therapy may also be utilized. Objective To evaluate the effectiveness of FRF against that of collagen induction combined with autologous plasma filler in treating linear scars. Patients and methods Nineteen patients with linear scars participated in this comparative study. A comprehensive history and assessment were conducted to evaluate the scar utilizing a modified Vancouver scar grading system, both before and following the end of treatment. A microneedling fractional radiofrequency device was employed to treat one scar or a segment of the scar measuring no less than 5 cm in each patient (section A). A separate scar in the same patient, or a portion of the existing scar measuring no less than 5 cm (section B), was addressed using microneedling collagen induction in conjunction with the injection of autologous plasma filler. Results Both treatment modalities were beneficial for linear scars; however, FRF exhibited considerably greater efficacy than collagen induction with plasma filler ( P =0.046). Conclusion Both FRF and microneedling collagen induction, in conjunction with the injection of platelet-rich plasma filler, are efficacious in treating linear scars. Both are appropriate for darker skin types, as neither relies on chromophores. FRF demonstrated markedly superior outcomes with reduced adverse effects.
