Topical drugs can't completely remove scars, which only shows that it is better to use them than not to use them; Skin grafting is not effective either. After skin grafting, the color of the implanted part will be darker than the surrounding area, and the incision will scar and look ugly. At present, the best method, I think, is to adopt the method of skin and soft tissue expansion, that is, implant the expander under the normal skin tissue around the scar, and then inject water into the expander regularly through the expansion pot to fully expand the skin, just like the cause of pregnancy. Finally, take out the dilator, and there will be redundant skin in the expanded part, remove the scar, and cover the defective part with redundant skin, thus leaving only a linear incision. It will be more perfect if this incision line is hidden through a good design scheme. Friend, go and find a good burn plastic surgery hospital. I hope it will help you.
