I'm considering a chin reduction through the submental approach to address some soft tissue and bone issues. I've been told the scar will be barely noticeable under the chin once healed and I've seen pictures from the surgeon's gallery that back that up. However, elsewhere online (not from my surgeon) I've seen cases where the scar is quite noticeable. Is this to be expected because some people scar more than others or are there precautions that can be taken to reduce scarring?
