Clinical study
A randomized study comparing the efficacy and safety of blue light and topical vitamin D treatments for mild Psoriasis vulgaris
Daily treatment for 12 weeks with blue light for 15 and 30 minutes is as efficient and safe as standard treatment for mild Psoriasis vulgaris with calcipotriol. View abstract
In-vitro Research
Blue-light irradiation regulates proliferation and differentiation in human skin cells.
Our data provide 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. View abstract
In-vitro Research
Blue light irradiation suppresses dendritic cells activation in vitro.
Unlike UV irradiation, blue light irradiation at high and low doses only resulted in impaired DC maturation upon activation and a reduced subsequent stimulatory capacity in allogeneic MLRs with strongest effects at higher doses. View abstract
Clinical study
Prospective Randomized Long-Term Study on the Efficacy and Safety of UV-Free Blue Light for Treating Mild Psoriasis Vulgaris.
UV-free blue light home treatment is safe and improves Pv plaques. View abstract
