Hello, according to the photo, you need mechanical grinding. The effect of microcrystal grinding is not good. Mechanical grinding can meet the depth requirements. Of course, if you grind it twice or so, you should pay attention to sun protection. Generally, hospitalization is not required. The wound usually heals in about ten days, and the cost is more than 2000 yuan at a time. According to the size of the area, it usually takes two weeks to scab.
