New research is promising to acne patients who want to continue blue light treatments at home to clear up their blemishes. The Journal of Clinical and Aesthetic Dermatology (JCAD) conducted a clinical study of the Tria Skin Perfecting Blue Light for Acne device in their May 2012 issue. The Tria device uses blue light therapy to kill the P. acnes bacteria, which is responsible for acne vulgaris breakouts. The study looked at 32 men and women between the ages of 13 and 45 who had mild to moderate acne lesions on their face. After only one week of using the Tria device, the participants showed a significant reduction in acne lesions an inflammation. After eight weeks, all of the participants reported an improvement in the frequency and severity of their breakouts as compared to their baseline.
For optimal results, the Tria should be used in conjunction with the stronger, in-office blue light treatments.
