Violet is really effective, so it's true. I heard that it completely removes fat cells and is really good for the double chin. First of all, the injection is painful... It feels painful inside... And the lump? There is about a month. But after about 10 days of being beaten, people say that their faces have lost weight. The third week? It worked well for a month. But after that, I personally gained weight, so I don't know.. ㅠㅠ Also, since this is very effective on the double chin, it seems to be more effective if it is applied with a deep cheek contour injection on the side when it is applied! But it definitely seems to work well for the double chin. chin pointed
