Outcome Measures

Primary Outcomes (1)

  • Reduction in the size of facial hypertrophic scars

    To objectively assess baseline status and subsequent changes in facial skin, the validated photometric visual scale from Manchester, designed for evaluating scar quality, will be employed. This scale assesses six skin parameters, including coloration, contour, distortion, texture, and brightness, assigning values from 1 to 4, where 1 represents the most favorable characteristic and 4 the least desirable

    From enrollment to the end of treatment at 4 weeks

Study Arms (1)

Intralesional administration of 5-fluorouracil will be conducted in the periocular scar group
