A Novel Technique that Reduces Sebum Production and Improves Atrophic Acne Scars


eMediNexus    30 December 2022

Fractional microneedling radiofrequency (FMR) is now widely used for treating acne scars because of its favorable outcomes and short downtimes. The present study investigated FMR use in reducing facial sebum production and treating acne scars.


It compared sebum production after three sessions of FMR (Fractora® 24-pin coated tip) performed 1 month apart. It evaluated results with a sebumeter (Cutometer®), sebaceous gland histology and subjects′ assessment; and graded acne scars according to the Echelle d′Evaluation Clinique des Cicatrices d′Acné scale, Goodman and Baron′s qualitative grading system, acne scar volume measurement and subjects′ assessments.


The study observed:


  • Significantly decreased sebum production since the first treatment, which sustained throughout the study period, as viewed by sebumeter results.
  • Decreased density and size of sebaceous glands in histology.
  • Significant decrease in the mean acne scar volume without a significant increase in the mean melanin levels.


This study demonstrates the potential of Fractora® 24-pin coated tip as an alternative for patients with acne scars who wish to reduce their facial oiliness concomitantly. It imparts a significant decrease in facial oiliness and acne scars′ volume after a single treatment session, with up to a 15.48% decrease in facial oil production.
