Exam needed. Hard to know without exam. How long ago was the injury? Sounds like you have a derm appointment. The derm will tell you if anything needs to be done now. Normally, one would wait up to one year to decide if scar modification is needed. Consider seeing a board certified facial plastic surgeon.
