It's my 6th month of Xeomin Chin Botox. It's expensive, but it's definitely effective. I got some bruising on one side of my chin when I got it, but this isn't the Botox's fault. It seems to be a difference in which area and how the treatment is done. After 6 months, it seems to come back like a knife, so I have to get it regularly. I think Xeomin is the best because there is less concern about Yen resistance!
