How many days does it usually take for the effects of Botox to appear?

I have a face shape with a particularly prominent square jaw.

I use a retouching app on my jaw every time I take a photo

I am spending all my time trying to reduce it.

I'm so scared of surgery and worried about side effects.

Jaw Botox that simply reduces muscle

I have made a reservation to try it for the first time in my life.

But I ended up having a really important blind date scheduled for next weekend.

If you get it now, your jaw will become slimmer by next weekend

Will I see significant effects from Botox? Muscle mass varies from person to person

They say there is a difference because it is different, but usually around when does the jawline start to become defined?

I would like to hear your experiences with Botox regarding whether it makes you slimmer.
