Masseter botox and Voluma cheek filler. How did my face end up worse? (Photo)

What you are seeing is a result of the masseter Botox you had done. Although, masseter treatment can be great for some, due to your anatomy you lost the support of your jawline by relaxing the masseter muscle. I would avoid doing in again unless you need it for pain relief. You can look into other treatments to contour the lower face such as microneedling treatments with radio frequency or fillers.

Thanks for your question. When we treat the masseters with botox they do shrink in size. This rarely happens to such a degree that it would make loose skin/jowls worse, but the potential is there especially if there was some pre-existing skin laxity. Regarding the cheek filler, 0.7 ml is a fairly small amount for volume correction (and don't expect any correction with that to last "2 years" because the Voluma 2 year studies treated their patients with 5 or more syringes to get that '2 year' duration!). Looking at your images, you have beautiful features and certainly it is primarily skin laxity that should be addressed here. You need to restore lost collagen and elastin to the skin- getting it to tighten and lift. Avoid trying to "fix it all with filler" - I see a lot of people who get a bunch of cheek and jawline filler to try to correct this and they end up looking like distorted pumpkin faces.
So, how to do this? You could start with a "No Downtime" procedure like Sofwave. A full "advanced protocol" delivering 4 passes at a good energy setting. I'm sure you would see a nice improvement with that, but if you were looking for something even stronger AND you can tolerate some downtime then consider a combination of Morpheus8 series of 3 with one FaceTite session (performed off the same platform) to tighten the jawline. I hope that helps!
