A Hi CaitScott,
First of all, you have beautiful skin and features, but whether you would benefit depends on what you are hoping to achieve. If you are wanting to increase the angle of transition from the cheek to the chin, that can be done through injecting filler for more prominent cheeks, but also with slimming of the jaw. Do you grind your teeth? Patients who clench their jaw or grind their teeth will develop more prominent masseter muscles thus making the jaw be the same width as the cheeks.
Find a provider who knows how to use botox to soften the masseters and plump the cheek area a bit. I would start with 1 tube of Juvederm Ultra HC with 1/2 a syringe in each cheek. Look at the results and decide if you want to add a little more. If you like it the look the first 3 days then you will probably like a little more added for after the swelling goes down. Don't love it or hate it for 2 weeks.
The fillers are temporary so if you really don't care for the result, it is not permanent. Make sure the provider listens to you. I use Juvederm Ultra frequently, especially in someone who has never had filler.
I hope this was helpful and gives you the look you are desiring.
