Abstract: The purpose of this study was to investigate the efficacy of phototherapy with a newly-developed 1450-nm diode laser in patients with mild to moderate acne. An open study was performed in acne patients who were treated up to five times with a two week interval. Acne lesions were reduced by 63%. Only one patient discontinued treatment due to vesicle formation as an adverse effect. Phototherapy using this diode laser source was effective and well tolerated in acne patients, suggesting that this phototherapy may be a new modality for the treatment of acne.
