Prognostic Factors Associated with Clinical Improvement Following Energy-Based Device Treatment in Thai Patients with Atrophic Acne Scars: A Retrospective Study.

ABSTRACT:

Introduction

Acne scarring is a prevalent complication of acne vulgaris, often resulting in significant psychosocial distress. While energy-based devices (EBDs), including fractional laser (FL) and fractional radiofrequency (FRF), are increasingly used for atrophic acne scars, limited data exist on prognostic factors predicting treatment outcomes, particularly in Asian populations. The study aims to identify clinical predictors of graded clinical improvement in patients with atrophic acne scars treated with FL and FRF.

Methods

This retrospective cohort study was conducted at a university hospital in Bangkok, Thailand, from 2012 to 2023. Clinical improvement was assessed using standardized photographic evaluations and categorized into four levels: < 25%, 25-50%, 51-75%, and >
