Do visible changes occur after just one fat-dissolving injection?

The outer part of my thigh looks particularly protruding
Even if I exercise or follow a diet, it seems like the weight just won't go down in that specific area.

Rather than losing more weight
I'm looking into fat-dissolving injections because I just want to tidy up that specific area a little.

However, there are many reviews saying that you need to receive it a few times, so
I'm not sure if I should try it once to see if it works before deciding.

Actually, even after receiving it the first time
I'm curious if anyone feels that the fit of my clothes has changed.
