INTRODUCTION: Psoriasis is one of the most common chronic skin diseases affecting up to 2% of the general population. In recent years, an important direction for the development of treatment for psoriasis has been the use of blue light emitted by LED lamps.
AIM: To evaluate the efficacy of blue-light emitting device in psoriasis vulgaris treatment.
MATERIAL AND METHODS: The study involved 30 adults with a mild form of psoriasis vulgaris not previously receiving biological treatment and other forms of phototherapy. Participants of the study used a device emitting blue LED light for 3 months. Each participant received a device for use at home, with which he/she exposed 2 psoriatic lesions located on the limbs. Before and after the study, the severity of the disease was evaluated using PASI, DLQI and LPSI.
RESULTS: During 3 months of the therapy, a statistically significant decrease in the mean LPSI (in both treated locations) and DLQI was noted (LPSI decrease from 5.25 ±1.82 to 1.98 ±1.74, p < 0.0001; DLQI from 7.36 ±5.59 before the study to 5.23 ±4.62 after the study.
CONCLUSIONS: Our results confirm that phototherapy using blue LED light is both a safe and highly effective way to treat psoriasis.
