Medstar Health Research Institute

INTERVENTIONAL
Conditions
Summary
Patients who have hypo-pigmented burn scar will have two scars chosen and randomized to treated scar and control scar. The subject will then have both scars treated with fractional ablative CO2 laser (FLSR). The treated scar will have bimatoprost delivered through the laser channels, while the control will have the vehicle (normal saline) only delivered. The treatment will continue for 14 days with twice daily application. The scars will then be monitored at a 2-week follow-up visit where levels of melanin will be evaluated. Tissue punch biopsies will also be used to evaluate the mechanism of action of bimatoprost. Treatment will occur for 6 sessions at 4-6 week intervals including follow- up visits and evaluations.
