Multimodal Management of Facial Acne Scarring Using Energy-Based Devices and Injectable Therapies: A Case Report

Acne vulgaris is a highly prevalent chronic inflammatory disorder that frequently results in permanent scarring, with atrophic scars representing the predominant type. The management of atrophic acne scarring is challenging due to variability in scar morphology, depth of dermal involvement, and patient-specific factors, often necessitating individualized and multimodal treatment strategies. We report the case of a 35-year-old male with facial atrophic acne scars treated using a combination of picosecond laser therapy, erbium:YAG laser resurfacing, injectable poly-L-lactic acid, hyaluronic acid filler, and microneedling radiofrequency over a structured treatment course. The patient demonstrated progressive improvement in scar appearance and skin texture, with good tolerability and no reported adverse events throughout follow-up. This case highlights the clinical application of a multimodal approach that integrates energy-based devices and injectable therapies to address multiple structural components of atrophic acne scarring.
