But if the scar is small, you only need to inject it at a few points, and it will cost you more than ten yuan at most. But if you have a big scar, you should take your time. It takes dozens or hundreds of stitches or even more to achieve sufficient density on the whole scar, so the injection fee will definitely increase. If a nurse (maybe a doctor) gets a commission of 2 yuan for one injection, it is impossible to ask others to give you dozens of injections to raise 2 yuan. So it is also reasonable.

The main function of this medicine is to prevent the scar from growing, and to soften the scar a little, and the effect is not obvious. You don't have to call once in your life, you need to call often.
