RF microneedling combined with fractional CO2 laser boon for Acne scarring patients
New research found that a combination of radiofrequency (RF) microneedling with fractional ablative carbon dioxide (CO2) laser for acne scarring is safe and effective with visible results even by undergoing a single treatment. The study was published in the "Journal of Cosmetic Dermatology."
Acne scarring can cause a huge psychological burden on the patient. Combination radiofrequency (RF) microneedling with fractional ablative carbon dioxide (CO2) laser is a new approach for acne scar treatment. So, researchers from London conducted a systematic review of the literature on the safety and effectiveness of this treatment for acne scarring and also assessed the safety and effectiveness in a 2-center case series.
For the systematic review, the researchers collected the articles that assessed the safety and effectiveness of a combination RF micro-needling and fractional CO2 laser for acne scarring and assessed the quality using the Downs and Black checklist. For the case series, patient records who underwent a single treatment with RF micro-needling and fractional CO2 laser for acne scarring from two clinics were reviewed. One was from London, U.K., and the other from Washington D.C., U.S.A. Outcome assessment was via the Scar Global Assessment (SGA) scale.
Results:
Systematic review:
- 3 articles were included and reported improvements in acne scar severity.
- Erythema, edema, pain, vesicle formation, erosion, petechiae, desquamation, post-inflammatory hyperpigmentation (PIH), and acne flare were the adverse effects.
- Quality scores ranged from 14-15 (maximum of 21).
Case series:
- 26 patients were included.
- Mean SGA Score was 3.0 at baseline and 1.3 at follow-up.
- All patients had an improved SGA score.
- Adverse effects included erythema, pain, edema, skin crusting, PIH, and an acne flare.
- All patients resumed normal activities within 7-days of treatment.
Thus, the researchers concluded that for patients with acne scarring Combination of RF micro-needling and fractional CO2 laser appears a safe and effective treatment and even a single treatment can result in noticeable improvements in acne scar severity within a short recovery time.
