Hey not sure if this is the right place to post but I'm looking for advice on my jaw. If anyone knows any better subreddits which might be more suited please let me know.

I've basically had issues and been self conscious about my jaw for as long as I can remember and recently it's been getting really bad. Basically I have a small recessed jaw that makes my face look tubby and baby faced in a way a guy in his 30s shouldn't. Especially when I'm not overweight. I feel particularly bad about it at the moment, as the country I am in is going through a heatwave so it makes me feel like my face is puffy from sweating all the time.

I'm posting because I want to see if there is any advice to help get at least a slightly more defined and masculine jaw.

Unfortunatley I already went down the jaw surgery road. I was offered it for free in my country, after a few consultations, however I decided not to go for it after I was warned by the surgeon I saw that I possessed all the criteria which would make me at high risk of relapse. (Basically after the surgery there would be a high chance my jaw would revert leaving me in a worse position than I started).

I already went down the Botox and filler route as well. Basically a few years back when having my jaw surgery consultations, they pointed out my masseter- muscles were under hypertrophy and overworked. From teeth grinding, stress and the shape of my jaw. Which made sense as my jaw was always in pain and clicking, especially at in the morning or on nights out drinking. About 4 years ago I had 3 jabs of masseter botox over about a year, which succeeded in helping with the jaw pain. I no longer really get pain in my jaw anymore. But I worry that the loss of the size of masseters has exacberated how puffy and un-masculine my face looks. I also had some filer in my chin to help my profile. I assume its mostly dissolved, but I worry it's affected my smile still leading to it being more strained and less natural.

I also had invisalign at this time which helped slightly with my jaw clenching.

I've attached photos to show, first few are current, then some from before the botox and fillers (and invisalign) about 4 - 5 years ago. And then the last 3 last year where I felt at least slightly better about how my jaw looked. I wonder if it was just a colder month, or I was in better health, but my face didn't feel as puffy during that period. I've also covered my eyes just to keep some anoyminity, as I'm only interested in advice for jaw and lower third of my face.

With all of this, I wonder if anyone has any insight on how I can improve this issue? I'm not looking for a miracle, but I think I should be able to aim for some improvement on how my jaw currently looks, even if in a minor way.

Current Options

Facial Hair: Would be amazing but I cant grow much. I've tried minoxdil to help with this before, but I've had heart issues resulting and it's also made my face puffier than before.

Gym/ Exercise: I'm in fairly good shape, but I've never been able to achieve an athletic toned look. I'm focusing on trying to get body fat down to a level where my abs are showing atm. Hopefully that will help somewhat towards my face looking more defined.

Masseters: As mentioned above after the botox the pain went away but my masseters shrunk. I'm considering trying to grow them back through using chewing gum or jaw trainers. Although I dont know if this is a good idea, as it may bring back my TMJ pain, and also not give me look I want.

Dissolve my chin filler: I've considered this as well, as it does affect how my smile looks. Although as it's been over two years, I'm not sure how much filler is still there and what little is there is still helping my profile.

Mewing: I've corrected my tongue posture over the last few years somewhat. I keep my tongue in position behind front teeth at roof of my mouth most of the time, and breath through my nose. But I dont think I've ever got the hang of hard mewing, I worry my palate is too small for my tongue to do it correctly. I'm also in my 30s, so a little too old to get some of the benefits I've seen other people online get.

Gua Sha Tool/ Micro current tool: I've seen these and tried them online. I've never been consistent with using these. Would be interested if anyone has known anyone to successfully get results from these and if I should commit to using them.

General Health: I have some bad habits which could also be contributing and making things worse. I work slouched behind a computer most days. And when in bed at night I'm on my phone with poor posture. I'm also fine at looking after myself most days, but occasionally once a week I have some bad days like today, where I forget to really drink or eat for a fair few hours which I worry is contributing to my issues.

Anyone if anyone has any good ideas on what might help please let me know!
