I want to ask how to fix my lips/smile please & my heavy jawline. I have never been able to smile properly, it's not to do with aging. I'm 30. I had braces, & I had a MACS lift. Recently I had botox injected into the masseter muscles which reduced it slightly. My face improved slightly after the MACS lift but still I can't smile like other people do. My teeth don't move with my lips so I have never smiled with my mouth open showing the teeth.
