I am a 30-year-old female with antegonial notch and jowling. I think the notch accentuates the jowling. Do you think notch fillers here would improve things? I know there is an artery there, but maybe it would be safe if an ultrasound was used? Would you recommend something else to help the jowls? I think prejowl sulcus filler can make the chin look too wide and masculine, so I don't think I'd do that...
