Targeted blue light phototherapy with MultiClear is effective for the treatment of inflammatory acne lesions. This new irradiation device offers some advantages over previous blue light systems.
The findings of this retrospective observational study indicated that combination treatment with topical vitamin D(3) derivatives and narrow-band UVB is effective against psoriasis without any obvious side-effects. These findings provide further evidence that calcipotriol has advantages over maxacalcitol regarding the narrow-band UVB-accumulated treatment dose and improvement rate of psoriasis area and severity index (PASI) scores.
Narrow-band ultraviolet B (NB-UVB; 310-315 nm) is commonly used to treat vitiligo, but the mechanisms underlying the therapeutic effect have not been understood completely. Here, we evaluated the effects of broadband UVB (BB-UVB), NB-UVB, 308 nm xenon chloride (XeCl) excimer laser, and 308 nm XeCl excimer light on the expression of endothelin-1 (ET-1) in a cultured human epidermal tissue model. Our results provide a theoretical basis for the effectiveness of UVB irradiation, including excimer light and excimer laser, in the treatment of vitiligo.
Low-energy, double-pass therapy is an alternative method that is beneficial for patients who complain of considerable pain. Furthermore, the method may have a lower risk of transient hyperpigmentation induced by cryogen spray, even in Asian patients who tend to develop inflammatory pigmentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
