The best time to repair scar in children is determined by the size and location of the scar, and the timing of treatment needs to be decided in the light of the child’s specific situation, and cannot be generalized. 1. If the scar has affected the function of the child’s major organs, such as the neck or facial organs, the function of large joints, there is no time limit, timely surgery to solve the functional problems. 2. For purely aesthetic problems, the appearance of the scar can be improved by conservative treatment, that is, non-surgical methods to improve the appearance of the scar, such as medication, photoelectricity treatment, etc. The scar can be treated when the child is older. Surgery can be considered when the child is old enough to tolerate and cooperate with the surgery. Since the scar affecting the aesthetic appearance will affect the psychological development of the child, it is a more appropriate time to do it before enrollment in kindergarten or elementary school. If you are troubled by scarring, you should go to the hospital and be evaluated by a specialist before deciding whether or not to treat the scar.
