The prevention of scar hyperplasia after burns generally includes two points. The first is to keep the wound clean, the second is to prevent scratching, and to remove the causes of scar hyperplasia, such as infection, injury, and ultraviolet rays. In addition, it is recommended that patients use appropriate scars and soften scars. For deeper wounds, by softening the scar, the proliferative phase can be advanced, even skipping the proliferative phase, and directly entering the softening phase. For patients at higher risk, it is recommended to use a compression coat to greatly inhibit scar hyperplasia. Therefore, patients with the risk of scar hyperplasia should be followed up regularly, and appropriate anti-scar treatment should be carried out at the doctor's suggestion. At the same time, according to the treatment results, timely adjustments should be made and surgical treatment should be performed if necessary.
