Pouches around mouth? What is this from and what can I do? Recent weight loss and getting married in a few months. (Photo)

I've lost 30 pounds in the last year and my skin has changed. I had 1 cc of juvaderm plus in my cheeks a month ago and Botox in jaw for tmj/wide jaw. I've noticed fat pouches around my mouth and dents in skin when I smile. My dermatologist is injecting ultra plus in nasolabial folds, Im nervous of looking unnatural. Will this help my case and what should I do to rejuvenate my mouth area? I want to look like a better version of myself for my wedding in a few months. Suggestions please? Thanks!
