Evaluation of the effect of 577-nm pro-yellow laser on demodex intensity.

The skin disease of the pilosebaceous unit created by demodex mites is called demodicosis. Recently, it has been brought to the agenda that laser therapies can be effective in reducing the intensity of demodex parasite. With this study, we aimed to evaluate the effect of pro-yellow laser applied to the face on the intensity of demodex parasite. Twenty-five patients who had referred to the dermatology polyclinic with a complaint of rash on the face and who had been given proyellow laser therapy during the past year were included in the study. Average pre-laser therapy demodex number per cm² was 3.9 ± 5.0, while average post-therapy demodex number per cm² was 2.6 ± 4.9 (p = .117). The 577-nm pro-yellow laser caused a change in demodex density. We found that the number of demodex following laser therapy decreased in some patients, while it increased in some others.
