2, take some antibiotics to prevent infection before taking out stitches, without an injection.
3, there is no food that can obviously accelerate healing, you can appropriately increase animal protein, western medicine can not be taboo, if you are really worried, you can avoid spicy food.
4, as long as the skin is strict when sewing, it will not leave obvious scars, and pigmentation can be left within one year. It doesn't matter, as long as it takes a summer, it will basically be fine.

Wish: Happy every day!
