Children have delicate skin and are prone to scarring when they suffer from various injuries. As a parent, we are particularly concerned about the best time to repair scars, that is, how to deal with them so that the child can avoid them or make them as inconspicuous as possible, thus not affecting the baby’s beauty. Children are more likely to have keloid scars because of their strong metabolism and skin proliferation. If the scar does not affect the function or only the aesthetics, it can be treated after adulthood. If the scar does not affect function or aesthetics, it can be treated after adulthood. If it affects function or aesthetics and thus the child’s psychological development, we can intervene and treat it early. Early intervention means applying anti-scar medications, such as silicone gel preparations and skin care, three days after the stitches are removed or the wound is healed and scabbed over, and continuing treatment for three months is generally able to be controlled. If the control is not very good and the hyperplasia becomes more and more serious, we have to consider surgery plus laser radiation therapy. The most important feature of children is that they grow fast and their bodies have a strong self-healing ability during the developmental stage, so active treatment of children’s scarring can generally recover better.
