Background:Blue light has no known toxic effects on human skin, but reduces the proliferative capacity of keratinocytes in vitro. We therefore investigated the efficacy of blue light in the treatment of psoriasis vulgaris (PV). Methods: Forty patients with mild to moderate PV and bilateral plaques were assigned to two groups. Group 1 (n = 20) received irradiation at home with blue light (light-emitting diode, LED, emission maximum: 420 nm) once daily for 4 weeks. In parallel, group 2 (n = 20…

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.
Blue Light in Dermatology
- BiologyLife

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.
A clinical review of phototherapy for 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 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.

Performing intralesional PDT is less time-consuming than several other pretreatment procedures and the time necessary to allow the conversion of the prodrug into the final photosensitizer is likely to be much shorter, as incubations.

This review focuses on the scientific background for the use of "yellow artificial lenses" and can show that many studies in cell and molecular biology, animal experiments and first clinical trials point to a preferential use of yellow-tinted lenses especially in the elderly and AMD patients.
