“…Generally, shorter wavelengths (<615 nm) are mainly absorbed by melanin, targeting epidermal pigment, while longer wavelengths can be used to remove both epidermal and dermal pigment, and hair. The treatments of Becker's nevus with either lasers or light instruments can improve pigmentation and hypertrichosis to some extent 17 . But the sample sizes in these studies were too small to draw a firm conclusion.…”

“…So far, lasers and lights are the primary modalities for the treatment of this disorder. Each wavelength of laser or light preferentially targets specific tissue or element of the tissue 17 .

“…The laser wavelengths used for Becker's nevus range from 504 to 10 600 nm. The clinical outcomes of laser therapy for Becker's nevus vary greatly with studies, 17 possibly due to limited number of patients and setting of the treatment parameters. Although intense pulsed light exhibits both depigmentation and hair removal properties, 18‐20 there are only sporadic reports of its usage for Becker' nevus, with inconclusive outcomes 21,22 .…”

Background Becker's nevus is a common skin disorder. Lasers and light instruments are the major modalities for the treatment of Becker's nevus, but the outcomes were mixed. Objective To evaluate the efficacy of the intense pulsed light for Becker's nevus in a large Chinese cohort. Methods We retrospectively analyzed the efficacy of the intense pulsed light for Becker's nevus in a single center. Results A total of 45 patients, including 26 males and 19 females (male to female ratio = 1.4), aged 5‐42 years, were included in this analysis. Twenty‐seven patients (60%) were with hypertrichosis. Treatments with intense pulsed light resulted in over 75% improvements in pigmentation and hair density in 1 and 2 cases, respectively. One patient displayed 51%‐75% reductions in hair density. The rest displayed ≤50% improvements in pigmentation and hair density. Recurrence occurred in all cases within 6 months after the last treatment. Adverse reactions were temporary and mild hypopigmentation, hyperpigmentation, hypertrophic scar, pain, and erythema. Conclusion Intense pulsed light does not exhibit long‐term benefits for Becker's nevus. Further studies in the large cohort are still required to validate the present results. Moreover, whether changes in the treatment parameters can improve the efficacy of intense pulsed light remains to be explored.

“…• Prognosis and treatment: Benefit from the Q-switched ruby laser has been reported, but reactive patchy hyperpigmentation may recur. While lasers are relatively safe, their efficacy for Becker nevus is moderate (Zhong et al 2019;Wulkan et al 2018;Momen et al 2016). Expert skin camouflage can be helpful.…”

To assess the efficacy and safety of a 1927-nm fractional thulium fiber laser treatment for Becker's nevus. Methods: A retrospective analysis of patients with Becker's nevus who were treated with a 1927-nm fractional thulium fiber laser was conducted. Grading for lightening was set quarterly by physician global assessment of the pre-and postphotographs (I: <25%; II: 25%-50%; III: 51%-75%; and IV: >75% for marked lightening). Grading validation was exercised using intra-and interobserver agreement analysis among 10 dermatologists to determine the percent of agreement and the intraclass correlation coefficient. Grades I and II were classified as treatment failure. Results: A total of 21 patients were recruited for analysis. The average number of treatment sessions was 2.1 per patient. A total of 13 patients achieved successful outcomes (grades III and IV) while 8 patients experienced treatment failure (grades I and II). Partial recurrence and transient hypopigmentation on adjacent skin were the main adverse effects. Only one patient reported worsening of the nevus. Overall agreement among the raters for the outcomes was graded from "very good" to "excellent," and the intraclass correlation coefficient, kappa, was 0.8. Conclusion: A 1927-nm fractional thulium fiber laser may be effective to ameliorate the pigment of Becker's nevus and achieve acceptable cosmetic outcomes. However, further studies are required in this area to improve and optimize the results.
