Help help: how to get a sharp jaw line”? - Help.com

unless your really skinny you probably won’t have one it also depends on the bone structure…if you have bad bonestructure you may need to talk to a plastic surgery specialist.

Umm….yeah I think there might be some jaw work-outs. Google’n always works for me.
Good Luck

There are exercises… but they don’t exactly do a lot…

Research how to stop retaining water (ex: lower sodium, drink water, etc.)

Exercises (research for more): Tilt head back, over pronounce the vowels (ae, ee, ie, Oh, You)
When you wash your face, pull the skin under the jaw up
Use skin firming lotion
etc.
