Using an intense pulsed light (IPL) module for the treatment of pigmented lesions

Abstract

BackgroundPigmented lesions are largely benign and may lead to extreme distress. Various light and lasers may be used to treat pigmentation, often Q‐switched lasers are considered the method of choice, while intense pulsed light (IPL) devices may offer a less invasive treatment with a shorter downtime.ObjectiveThe purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions.MethodsA retrospective study of 20 patients with pigmented lesions underwent treatment with an IPL module. Treatment was assessed by blinded evaluation of clinical photographs using a GAIS scale of 0–10, as well as through patient satisfaction ratings on a scale of 0–10. Throughout the treatment, pain levels and adverse events were monitored.ResultsThe mean GAIS score was 7.55 ± 1.15 (mean ± SD), and the mean patient satisfaction score was 7.3 ± 1.26 (mean ± SD). There was a strong positive correlation between GAIS and patient satisfaction scores (r = 0.83), and no significant difference between them (p‐value = 0.516). The number of treatments did not significantly affect GAIS and patient satisfaction scores (p‐values 0.364 and 0.126). Additional positive unexpected outcomes were improved skin firmness and reduced wrinkles.ConclusionThe results of the study indicate that the IPL module is both safe and effective in treating pigmented lesions and may have the potential to stimulate collagen production.
