Resumen

Objectives: Attendees will understand the mechanism, clinical effectiveness, and long-term safety of the 1726 nm laser in treating acne and rosacea. They will also learn to compare it with traditional wavelengths and recognize its therapeutic relevance in addressing the psychological burden during adolescence. Introduction: Acne vulgaris and rosacea are inflammatory skin diseases with significant psychosocial impact, particularly in adolescents. Traditional treatments such as isotretinoin and conventional lasers often have limitations. A novel 1726 nm laser wavelength offers a selective and non-invasive alternative with promising long-term results. Materials / method: We analyzed published clinical studies evaluating the 1726 nm laser for acne and rosacea, including prospective, multicenter trials. Parameters included reduction of inflammatory lesions, Investigator Global Assessment (IGA) scores, duration of effect, and side effect profile. Additionally, results were compared with traditional wavelengths such as 1064 nm Nd:YAG, 585–595 nm pulsed dye, and diode lasers. Results: The 1726 nm laser demonstrated significant reduction of inflammatory lesions, up to 97% at 24 months. 87% of patients improved by at least one IGA grade. Compared to traditional wavelengths, results were more durable and better tolerated. Psychological improvements were noted even in patients with moderate disease severity. Conclusion: The 1726 nm laser offers a safe, effective, and durable treatment option for acne and rosacea, with particular relevance in adolescent patients due to its psychological benefits. It provides a new standard in light-based therapies, combining efficacy, tolerability, and long-term disease control.
