This is actually based on personal skin problems, as well as the size of the operation area, the shape of the operation incision and the influence of external conditions. The time is not necessarily. Four or five months after minor surgery, maybe it will be fine. The scar of the vaccine should be almost healed in three months. These scars should be traceless, but some people recover from surgery. Some people's scars after surgery will never disappear. Unless you use a laser or something. This is the scar constitution! I am like this personally. I have seen people who have the same caesarean section, and some people can hardly see it and recover well. And some people, that scar is like a big centipede. It's ugly. I don't know what the specific effect will be, unless I use a laser again.
