Abstract

The 1450-nm diode laser has been found to be effective for the treatment of inflammatory acne in USA, Europe and Japan. However, there is no report on its efficacy in Chinese acne vulgaris patients. We conduct this pilot study to evaluate the efficacy and safety of the 1450-nm diode laser in the treatment of inflammatory facial acne vulgaris in Chinese patients. Nineteen patients with inflammatory facial acne were treated with the 1450-nm diode laser at 4- to 6-week intervals. Clinical photographs and lesion counts were obtained at baseline and after each treatment. Subjective evaluation of response to treatment and pain was assessed using a questionnaire. In our study, clinical improvement was seen in all patients and was generally dramatic. Lesion counts decreased 34% after one treatment (p<0.01), 56% after two treatments (p<0.01), and 81% after three treatments (p<0.01). However, the treatment-related pain was comparatively hard to be tolerated in Chinese patitents, and the other main adverse effect was the hyper-pigmentation after treatments (36.84%, 7/19).
