Hello, sewing needles can promote wound healing, but it will still leave obvious marks. If the doctor sews them in the skin, the marks will be lighter. After stitches are removed, you can buy some scar stickers or silicone stickers in professional hospitals to prevent scar hyperplasia and make scars flat and not prominent. If the scar is still obvious in the end, I suggest you go to a professional hospital to repair the scar, which is safer and the effect will be guaranteed.
