This is a randomized, double-blind, controlled clinical trial with placebo. The main objective is: determination of bulge and dermal papilla regimentation of the bonding and the outer root sheet of stable plaque. Criteria for inclusion: 1) At least 4 years have passed since the onset of their disease. 2) At least 6 months of stable disease and no new lesions. 3) The patient's lesions are bilateral. 4) There is not an appropriate response to other therapies. 5) There is no history of disease such as: hypothyroidism, hyperthyroidism, diabetes, asthma, atopic dermatitis, rhinitis, psoriasis, ulcerative colitis, lupus, alopecia areata, anemia pernicious. 6) Not currently being treated with other methods. Exclusion criteria: 1) pregnant women. 2) The incidence of these diseases 3) Parts of the bodies that are routinely exposed to light. 4) Patients who once responded to NBUVB return is after the break. 5) Kelloid. At first a small areas of the head selected, after anesthesia by lidocaine and epinephrine is then using a punch mm5 hair in the area occipital, removed and the bulge and outer root sheet dermal papilla may be extracted by suspension of the 3 is injected into the area provided below. Scheme used in this study, a block design capacity is 3 for each block. The patient in this study is considered a block and a third treatment is performed on each patient. Block designs, random allocation of treatments in each block must be done. Plaque in the first two of which will be created later Abryshn dermal needles are traumatized. A - The main area where melanocytes dermal papilla and outer Root sheet plus the Bulge area into the area. B - With the other, just insert a needle to create and respond to trauma is trauma. C - With the other, as seen in the control and the treatment will not be around either. Patients every month (up to 6 months) will follow-up. In each session, the size of the lesion on both sides will be measured and photographed and the response rates to treatment by a doctor who do not participate in the study based on the recovery rate subdivided from 95 to 100% = excellent, and 65 - 94% = Good, and 25 - 64% Fair = and 0 - 24% = Poor.
