Acne Laser Devices in Dermatology.

Laser and energy-based devices play an expanding role in acne management by targeting sebaceous hyperactivity, vascular inflammation, and microbial colonization. While light-based systems provide modest benefit in mild disease, thermal near-infrared lasers offer indirect sebaceous suppression. Lipid-selective 1726 nm technology represents a biologically aligned advancement with promising clinical outcomes. Fractional and radiofrequency platforms remain primarily indicated for acne scar remodeling. This review critically examines mechanistic rationale, clinical evidence, safety considerations, controversies, and future directions within a phenotype-driven therapeutic framework.
