Background. The safety effects of individual emission spectra of visible light are currently not well understood. Based on the above works, one can only indirectly judge the presence or absence of an adverse effect of the selected spectrum during mototherapy.
Aims: in our work, the goal was to detect the presence of a negative effect of certain wavelengths (410 nm, 580 nm and 630 nm) during mono-exposure to mucous membranes and skin.
Methods. At the first stage, the effect of radiation with wavelengths of 410 nm and 630 nm on the mucous membrane of the oral cavity of laboratory animals was determined. At the second stage of the study, 30 women aged 3545 years with signs of photodamage of the skin took part.
Results. No undesirable consequences were recorded either immediately after the procedure, or after 20 days. The results of histological examination at all stages of the study indicated the absence of pathological changes.
Conclusions. The results showed that mono-exposure with wavelengths of 410 nm, 580 nm and 630 nm is safe and can be recommended for further study and practical application.
