Acne has been shown to have a significant impact on patient quality of life and mental health, especially as inflammatory lesions typically occur on cosmetically sensitive areas with the potential for permanent scarring. There have been numerous advances in the treatment of inflammatory acne with light\u2010based and laser devices. This technology permits effective treatment of active acne and scarring, with a short recovery and a decreased side effect profile as compared to medicinal standard\u2010of\u2010care and photodynamic therapies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>The case series study was aimed at evaluating the safety and efficacy of a 1064\u00a0nm Nd: YAG Quasi\u2010longed pulse laser treatment for acne vulgaris.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a prospective study of 19 subjects with moderate to severe. All subjects received 1064\u00a0nm Nd: YAG Quasi\u2010longed pulse laser treatments, at 8\u00a0J\/cm<jats:sup>2<\/jats:sup> fluence and accumulated 1000\u20134000\u00a0kJ according to treatment area at two weeks intervals. Primary end point was reaching a minimal AGSS score of between 1 and 2. Acne severity was assessed by two independent dermatologists according to AGSS scale before each treatment session and at the follow\u2010up visit (8\u00a0weeks following last treatment). Subjects\u2019 self\u2010assessment of Patient Global Impression of Change (PGIC) and overall satisfaction were also recorded.

Minimal AGSS scores were still detected after 8\u00a0weeks following final treatment. Subjects scored high satisfaction rates and PGIC scores (2.9 and 5.3, respectively).
