I understand I am experiencing a side effect of chin lipo. I am unable to pull down my lower lip. Is it more common to happen to one, or both sides? Does laser lipo increase damage? I have had neck lipo before, I experienced numbness to one side of my lip but never paralysis. Does the scar tissue due to multiple treatments increase the risk of permanency? I know that time typically improves this but I am trying to see how much of a risk I am at for permanent damage.
