Autologous human platelet rich fibrin (PRF-L) is contains platelet that are purpose to release numerous growth factor that valuable in numerous dermatologic application.Platelet rich fibrin lysate used for EO has not been reported. We presented three cases with EO treated with split-face of the PRF-L applied right before dermaroller on right face and intradermal injection on the left for 8 weeks.The treatment re-apply every 2 weeks. The improvement was measuring by 10-point grading scale and dermoscopic examination, including five-point grading scale to assessment of patient satisfaction.
