Hello, scars can be cosmetic. At present, the most advanced method to treat scars in the world is stem cell transplantation, which can bring the greatest improvement at present. Don't believe that some operations say that they can be completely repaired. This is impossible, but stem cells can improve scars to the greatest extent. I just accompanied my friend to Deya, South Korea for plastic surgery and stem cell transplantation to remove the scar on my shoulder. I had two stem cell transplants, because she did it immediately after the operation, and the effect was very obvious. The doctor said that the sooner you do it, the more obvious the effect will be.
