Since you haven't given the details of your scar, I can only tell you simply that if your scar is flat, but the color is different, it means that the pigment has precipitated. Just go to the hospital and have a laser, but if your scar is uneven, no matter whether your scar is convex (that is, scar hyperplasia) or concave, or uneven, you must have surgery, but even if you pass surgery, it is only to repair the scar. It is impossible to be inconspicuous and return to the original situation (at least so far, dermatologists all over the world can't solve it), so if you really want to get rid of scars, you must have this psychological preparation in advance, but you said that your scars are not big, and it is estimated that the treatment cost is not very high. The price of Shanghai Ninth Hospital (the authority of plastic surgery) in the first two years is 400 yuan per centimeter, which can only be used for reference ~
