This is the most common and the effect is average. However, according to the strict regulations of international lipolysis association, 0.5ml injection is the most effective, because German liposuction needle is used together with two drugs, which will maximize the curative effect and the highest concentration. This organization is the most authoritative liposuction needle in the world. One * * produced two liposuction needles, one is 303, and the other is a German net-lipolysis liposuction needle. However, at present, only the latter is available in the international market, and the former has been removed from the shelves, which seems to be used by a few people in China. In Germany, the selling price of this product cost is strictly controlled, and there will be no bidding. I believe everyone knows this. So I know the price of this product, and I won't talk about other Korean fat-dissolving needles that are popular in China. If you want to know this knowledge, you can ask me a question, or ask Dr. Dongqiao, who is a top expert in this field in China.
