Other Name: Laser therapy
Active Comparator: Topical steroid
clobetasol propionate 0.05% cream

Other Name: Local steroid therapy
- Clinical Lichen sclerosus score (LS score) [ Time Frame: 6 months ]Reduction (i.e. improvement) of physician administered clinical LS score (Sum score of 6 items on a scale from 0-2 (0=no, 1=weak, 2=pronounced): erosions, hyperkeratosis, fissures, agglutination, stenosis, atrophy). Possible sum score ranges from 0 (normal) to 12 (maximum symptoms present).
- Vulvovaginal symptom questionnaire (VSQ) [ Time Frame: At each visit through study completion, an average of 1 year ]21 binary questions (0=no, 1=yes) about symptoms, emotional impact, impact on quality of life, impact on sexual activity. Total possible sum score is 21.
- Symptom strength score [ Time Frame: At each visit through study completion, an average of 1 year ]Visual analog scale (0-10) of LS symptoms itching, burning, vulvar pain, dyspareunia. Total sum score ranges from 0 (no symptoms) to 40 (maximal symptoms).
- Vulvar punch biopsy [ Time Frame: Baseline and at 6 months ]Histological changes
- Photo documentation of vulvar skin [ Time Frame: At each visit through study completion, an average of 1 year ]Changes of visual appearance of vulvar skin
- Patient satisfaction [ Time Frame: At each follow-up visit (6 months and 12 months) ]Satisfaction of the treatment. Levels: 3 = very much better, 2 = much better, 1 = a little better, 0 = no change, -1 = a little worse, -2 = much worse, -3 = very much worse
- Pain during treatment (for laser arm only): Visual analog scale (0-10) [ Time Frame: At each laser treatment session (baseline, 1 month, 2 months, 4 months) ]Visual analog scale (0-10)
