Brief Summary
Aim of this study is to evaluate the therapeutic effect of the laser treatment in vulvar LS, mainly the reduction of existing symptoms. As measured by visual analogue scale (VAS) symptoms as itching, burning, pain will be determined six weeks after the last laser treatment. Secondary endpoints will be sexual function measured with the female sexual function index (FSFI) and the vulvar skin changes measured by the Lichen score (LS). Regular photo-documentation of the treated skin will demonstrate a potential change of the tissue.

Outcome Measures
Primary Outcomes (1)
Vulvar pain measured with the visual analog scale with a range from 0 (no pain, best Outcome) to 10(worst pain, worst Outcome)
Primary objective of this study is the number of patients with reduction or cure of the symptoms of LS as itching, burning and vulvar pain after treatment is reduced. The effect will be measured with the visual analog scale.
End 12/2020. The measurements will be taken before each treatment and at the Follow-ups at 12 weeks and 18 weeks
Secondary Outcomes (1)
Sexual functioning measured with the Female Sexual Function Index (FSFI), each question ranges from 0 to 5 and the full scale score will be calculated(ranges from 2 (worst Outcome) to 36 (best Outcome))
End 12/2020. The measurements will be taken before each treatment and at the Follow-ups at 12 weeks and 18 weeks
