New phototherapy research from Seoul National University, Department of Dermatology outlined
2007 NOV 12 -- Data detailed in 'Red light phototherapy alone is effective for acne vulgaris: randomized, single-blinded clinical trial' have been presented. "Recently, a demand for safe and effective treatment of acne has been increasing. Although visible light has attracted attention as a new option, the effect of red light alone has not yet been evaluated The objective was to assess the efficacy of red light phototherapy with a portable device in acne vulgaris Twenty-eight volunteers with mild to moderate acne were treated with portable red light-emitting devices in this split-face randomized trial," scientists writing in the journal Dermatologic Surgery report. "The right or left side of the face was randomized to treatment side and phototherapy was performed for 15 minutes twice a day for 8 weeks. Clinical photographs, lesion counts, and a visual analog scale (VAS) were used to assess each side of the face at baseline and Weeks 1, 2, 4, and 8, and a split-face comparison was performed The percent improvement in noninflammatory and inflammatory lesion counts of the treated side was significant compared to the control side (p <.005)," wrote J.I. Na and colleagues, Seoul National University, Department of Dermatology. The researchers concluded: "VAS decreased from 3.9 to 1.9 on the treatment side and the difference between the treatment and control sides was significant at Week 8 (p <.005) This study shows that red light phototherapy alone can be a new therapeutic option for acne vulgaris." Na and colleagues published their study in Dermatologic Surgery (Red light phototherapy alone is effective for acne vulgaris: randomized, single-blinded clinical trial. Dermatologic Surgery, 2007;33(10):1228-33; discussion 1233). Additional information can be obtained by contacting J.I.
