This is my first time getting square jaw Botox, and I'm worried my face will look too thin.

Lately, I've been self-conscious about my lower face looking a bit wide in photos, so I'm looking into square jaw Botox. My jaw muscles on both sides tend to stick out quite firmly when I clench my teeth, so a friend suggested I get a consultation.

But while looking it up, I saw some people say their face became slimmer after getting square jaw Botox, whereas others said their cheeks looked sunken or they ended up looking too gaunt, so I'm a little scared since it's my first time.

I don't have a lot of facial fat, so I just want my jawline to look naturally refined. Rather than making it look like my face has suddenly gotten smaller, I'd be satisfied if the lower part of my face looked a little less angular in photos.

For square jaw Botox as well, is the amount adjusted based on muscle size and face shape, rather than injecting the same amount on both sides from the start?

Perhaps because I have a habit of chewing on my right side, the muscle sizes on both sides seem slightly different. I am wondering if this can be checked in person during the consultation.

And when you get Botox, your face doesn't get slimmer immediately; changes appear gradually over time, right?

I feel like I might get disappointed if I compare myself in the mirror from the first day, haha, so I'm wondering if it would be better to wait a while before comparing photos.

Are there any people who received square jaw Botox for the first time and didn't have much facial fat?

I’d like to hear about your actual experience regarding whether the jawline was naturally refined without making you look too thin. Please also let me know what points I should definitely mention during the initial consultation.
