I had got 2 treatments of botox on my jaw. I was told this would help soften my square jaw as well as given my face a thinner look.my last treatment was about 7 months ago, I could tell that my jaw doesn't look as square as it did before and my cheeks not as fat as they were before but it does look like I have a double chin now, I heard about mesotheraphy being a good option to get rid of a double chin without having to get surgery. Would it be safe to get that after the botox I had for my jaw?
