The Application of Intralesional 5-fluorouracil for the Management of Hypertrophic Facial Scars in the Periocular Region Resulting From Trauma and Surgical Procedures in Individuals Aged Over 18 Years

During the initial visit, informed consent will be obtained and documented, alongside baseline photographs and measurements of the facial scar dimensions using a ruler. In the subsequent visits-second, third, fourth, and fifth-0.5 ml of intralesional 5-fluorouracil, diluted to 25 mg/ml, will be administered. Clinical photographs will be captured, and dimensions will be measured at each of these visits. A total of 0.5 ml of this solution will be injected weekly into the lesion to be treated, amounting to four doses over the course of one month.
