22M Seeking Advice to Improve Jawline and overall appearance

Hi everyone, I’m a 22-year-old South Asian male, and I’m looking for tips to enhance my jawline and looks overall. I have been insecured for my entire life. I feel like my side profile and entire face could be improved, and I’d love some advice on how to achieve a sharper, more defined jawline.

Here’s some context:

I just turned 22. currently weighing 171.8 lbs and height is 5 feet 8 I don’t work out regularly, but I’m open to starting a fitness routine. My diet is fairly average, but I’m willing to make changes if necessary.

I’ve heard about things like mewing, facial exercises, weight loss, and grooming techniques, but I’m not sure what would work best for me. I tried some but most of them suck.

I’ve attached two side-profile photos for reference (I never post my photos online It's my first time) Do you think weight loss, specific exercises, or other lifestyle changes could make a difference? Are there grooming or styling tips that could help highlight my jawline better?

Any suggestions or feedback would be greatly appreciated! Thanks in advance.
