HI I'm 22 years old & I want to have a stronger and more angular jawline and the same for my cheeks.I have asked a plastic surgeon and he said i only need injections in my cheeks because i'm really thin, but i don't know if injections can achieve that, because most of the people i know who got injections ended up with really fat cheeks!! should i just do what my surgeon told me? I would love to know what is the best and the safest way to do it. And thank you doctors you help a lot.
