1,213 Cases of Treatment of Facial Acne Using Indocyanine Green and Intense Pulsed Light in Asian Skin

Abstract

Background. Photodynamic therapy (PDT) has been used for acne, with various combinations of photosensitizers and light sources. Objective. We evaluated the effectiveness and safety of indocyanine green (ICG) and intense pulsed light (IPL) in the treatment of acne. Materials and Methods. A total of 1,213 patients with facial acne were retrospectively reviewed. Patients received three or five treatments of ICG and IPL at two-week intervals. Clinical response to treatment was assessed by comparing pre-And posttreatment clinical photographs and patient satisfaction scores. Results. Marked to excellent improvement was noted in 483 of 1,213 (39.8%) patients, while minimal to moderate improvement was achieved in the remaining 730 (60.2%) patients. Patient satisfaction scores revealed that 197 (16.3%) of 1,213 patients were highly satisfied, 887 (73.1%) were somewhat satisfied, and 129 (10.6%) were unsatisfied. There were no significant side effects. Conclusion. These results suggest that PDT with ICG and IPL can be effectively and safely used in the treatment of acne.
