Efficacy of Topical 5-fluorouracil Versus Topical Latanoprost With Microneedling in Localized Stable Vitiligo: A Randomised Clinical Trial

Latanoprost 0.005% Ophthalmic Solution

The affected area cleaned with betadine surgical solution followed by alcohol 70%. Local anesthetic, pridocaine cream, applied on the treated area under occlusion for 30 min before the procedure. Using automated microneedling device (Dr Pen Derma Pen Ultima A6®) , which has a disposable head that personalized for each patient and sterilized after each session. The derma pen will penetrate the skin with variable depths ranging from 0.25 to 0.5 mm (not more than the depth of the epidermis). It will pass vertically over the vitiligo area in a circular pattern until pinpoint bleeding appears. The LT solution will be applied immediately to vitiligo patch one drop (contains 1.5 μg of LT) for every 2.5 cm. This procedure will be repeated every two weeks for six months.
