Will lip injury cause permanent scar?
In most cases, after an injury, there will be a scar that forms. It does take several months and sometimes up to a year for all of the healing to occur. In the ideal situation, once the healing has occurred, the scar may not be noticeable but it would always be present. Since your injury was only a week ago, you definitely need more time for the lip to heal before judging how your scar will look.
