Scar hyperplasia is common in clinic, and the treatment methods are as follows: first, external use of scar-removing drugs, the most important component of which is silica gel. Second, the applied skin care can reduce the tension of scars on the one hand, and inhibit hyperplastic scars on the other hand, which has a better effect on hyperplastic scars. Third, drugs such as glucocorticoids, if sealed in the scar lesions, will receive obvious results. Fourth, the surface is relatively red, and you can see the hyperplasia scar of capillary dilatation, which can be irradiated with pulsed dye laser. Fifth, if the hyperplasia is obvious and the above treatment effect is not ideal, surgical resection and radiotherapy can be considered.
