It doesn't look like a hyperplastic scar in the photo, but more like pigmentation after trauma (maybe it's not clear because of shooting). If it is pigmentation, it can only fade slowly after a long time, and pay attention to sun protection. The more treatment and stimulation you do, the easier it is to deepen and delay its regression. If it is a hypertrophic scar, it can be improved by surgery. If you must make a laser, you can try a dot matrix laser. The plastic surgery department of Zhejiang Provincial People's Hospital has this machine, which needs multiple treatments. The cost is calculated by area every time. The specific price can be consulted by telephone at 8533333. If it is a scar, be prepared psychologically. It is impossible to eliminate the scar after it is formed. Only through repeated treatment can it become beautiful or fade, so no matter what treatment method (surgery or laser), it will definitely leave traces in the end.
