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

BACKGROUND: Pigmented 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.

OBJECTIVE: The purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions.

METHODS: A 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.

RESULTS: The 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.

CONCLUSION: The 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.
