Background: Blue light irradiation reduces the proliferation of keratinocytes and modulates T-cell immune response in vitro and has been shown to reduce the severity of psoriasis vulgaris (Pv) in two clinical trials. Objective: Evaluation of safety and efficacy of long-term UV-free blue light treatment at home for mild Pv. Methods: Forty-seven patients with mild Pv were randomized for receiving high-intensity blue light treatment (HI: 453 nm LED, 200 mW/cm2, n = 24) and low-intensity treatment…

Simulations indicate that high efficacy is achieved by regimes with long duration and high fluence levels, regardless of the chosen intensity, and constitute a framework for testing diverse hypotheses on the underlying mechanism of blue light-based phototherapy, and for designing effective strategies for the treatment of psoriasis.

UV light is primarily for stable plaque psoriasis and PDL for topical psoriatic lesions with small area, both of which are safe and effective, and PUVA has better curative effects than UVB for managing refractory Psoriasis plaques, if its side effects can be better controlled.

It was demonstrated that blue light induces an anti-inflammatory and antiproliferative effect; thus, it may be beneficial for hyperproliferative and chronic inflammatory skin diseases such as atopic dermatitis, eczema, and psoriasis and long-term safety should be monitored.

Blue light appears to be a promising treatment modality in PV that warrants further evaluation in larger studies, and plaque status as assessed by both the physicians and the patients improved continuously during the 4 weeks of treatment and steadily declined thereafter.

Blue light-irradiation may represent a suitable treatment option for AD providing long term control of disease, and immunohistochemistry of skin biopsies obtained at baseline and after 5 and 15 days revealed that, unlike UV light, blue light-treatment did not induce Langerhans cell or T cell depletion from skin.

It is found that light at wavelengths of 632-940 nm has no effect, but irradiation with blue light at 412-426 nm exerts toxic effects at high fluences, which provides evidence for a molecular mechanism by which blue light may be effective in treating hyperproliferative skin conditions by reducing proliferation due to the induction of differentiation.
