It is difficult to get rid of all the scalded scars. My brother was scalded by boiling water when he was a child and has never had an operation. The doctor said that he had a laser scar removal when he was 20 years old, and the effect was not good at that time. Later, I changed hospitals and did it several times. It was almost half a year before he gradually lost it. Now he can hardly see it. Not obvious, but the effect is ok. You can go to that hospital, and you must find a good expert, because people have excellent skills. In Zhongtongren Road, Milan Plastic Surgery Hospital.
In addition, I am giving you a reference material about scar removal, which has many detailed introductions.
