Retrospective Analysis of the Effectiveness of Laser Therapy in the Treatment of Acne Scarring

Abstract

Objective: This retrospective analysis aimed to estimate the efficiency of laser therapy in the management of acne scarring, assessing changes in scar severity, patient satisfaction, and adverse events. Methods: A cohort of 150 subjects with clinically diagnosed acne scarring who underwent laser therapy. Data were extracted from electronic medical records, and baseline characteristics, scar types, and management parameters were analyzed. Outcome measures included changes in scar severity scores, patient-reported satisfaction, and documentation of adverse events. Statistical analyses were conducted using appropriate methods, with sub-group analyses based on scar type and laser modality. Results: Following laser therapy, a statistically significant decrease in scar severity scores was seen across all scar types (P < 0.05). Patient satisfaction was high, with 75% reporting significant improvement. Adverse events were mild and transient, including erythema and post-inflammatory hyperpigmentation. Sub-group analyses did not reveal significant differences in management outcomes based on scar type or laser modality. Conclusion: Laser therapy demonstrates effectiveness in reducing acne scarring with a favorable safety profile. The research supports its role as a versatile management modality for diverse scar presentations, emphasizing the need for further research to optimize protocols and explore combination therapies.
