That depends on the specific analysis of your scar. I had a little scar on my face when I was a child. I can't see clearly now. I went to Korea last year to get rid of the scar, and the fat particles were gone. But the doctor said that mine can only be torn and sewed, and it will take half a year to recover. I think half a year is too long, so I didn't do it. You still have to go to the hospital.
