Masseter botox ruined my skin laxity

I'm at a loss after getting my masseters treated with botox last July.

I've clenched my jaw my whole life and my masseters were a bit overdeveloped, so I thought getting them injected would soften my appearance and also help with the tension.

A month after the injections, my jaw had shrunken A LOT and I noticed the skin on the lower half of my face was a lot looser and I had jowls forming. My skin has always been very taught and tight to the flesh so this aged me considerably.

I had hope that as the botox wore off, my face would return to its previous state but I'm 7 months out and my skin is still lax and sagging. I seriously want to cry. I compare pictures the month before botox compared to the month after and the difference is stark. I feel like I ruined my face at 31.

Have any of you experienced this? If so, did you do anything to fix it? Did it go back on its own? Or are we stuck like this?!
