KLOX Technologies has received CE mark approval in Europe for its topical photo-converter gel for the treatment of acne vulgaris. The gel is part of the company’s LumiCleanse System, a non-invasive acne vulgaris treatment that combines LED light and a topical photo-converter gel. According to a company press release, the non-abrasive and non-thermal treatment protocol—including skin preparation—can be performed in 15 minutes. Patients undergo treatment twice a week for six weeks. The system was approved for the treatment of all severities of acne vulgaris in Canada in September of this year.
