Have you looked around to see if there are any horror stories on this one?
I must admit I did scant reading on the "inventor"'s website , but no further. I would want to fully check out the downsides, bearing in mind how "safe" Botox and fillers were considered to be, just a few years ago, and how now folks are halting Botox and having fillers dissolved because of issues.
Whilst I empathise that you have a body part you really dislike, personally, I would approach this with enormous caution. (In fact, personally, I wouldn't do it.)
I have nothing against anyone wanting to be their best self, but injecting chemicals will always hold some jeopardy.
