I'm curious about contouring methods to make the jaw look narrower.

As I get older, I realize I can't escape the law of gravity. My face used to be oval-shaped when I was young, but as I age, it seems to be turning more and more rectangular. Watching my jawline gape open makes me instinctively put on a mask. After all, a mask can hide that square jaw. It's sad. I think about wanting to reshape my jaw 365 days a year. However, while I'm scared of procedures or surgery, the financial burden is a major concern. How can I change this a bit with makeup? Please share some contouring tips to make my jaw look narrower.
