To observe the efficacy and safety of a combination of intense pulsed light (IPL) with advanced optimal pulse technology (AOPT) and human-like collagen repair dressing in the treatment of melasma. Ten patients with melasma were treated using IPL with AOPT once a month for a total of 8 times, and received the treatment of external human-like collagen repair dressing after each operation. The efficacy was evaluated with the modified Melasma Area Severity Index (mMASI) score and satisfaction score, respectively, before treatment, after each treatment and at 4 months after the end of the whole treatment course. The melasma was significantly lightened in all 10 patients after 8 times of treatments. The mMASI score before treatment was (8.6 ± 3.8) points, which decreased significantly to (5.1 ± 2.7) points after 8 times of treatments, and there was a significant difference in mMASI score between before and after 8 times of treatments (P = .001). The mMASI score was (3.3 ± 2.2) points at 4 months after the end of whole treatment course, and there was no significant difference in mMASI score between after 8 times of treatments and 4 months after the end of whole treatment course (P > .05). The satisfaction score was (7.2 ± 1.4) points after 8 times of treatments and (7.1 ± 1.4) points at 4 months after the end of whole treatment course, there was no significant difference in satisfaction score between after 8 times of treatments and 4 months after the end of whole treatment course (P > .05). A combination of IPL with AOPT and human-like collagen repair dressing can effectively decrease the severity of melasma, and is associated with a higher patient satisfaction score and a lower risk of relapse after discontinuation of treatment.
