You are at least kinda new to this, aren't you? Check the internal surgeon's powerpoint - there are (almost) no good outcomes. They say it themselves:
If you consider that these complications don't always overlap in one patient,
we are basically looking at a failure rate of this procedure, in one way or another, above 50%.
And even if it "worked", what good is a dangling fleshgraft with no functional purpose and massively scarred harvest sites to begin with?
The source is attached to the quoted post. Thread's moving fast, just on the off chance you missed it.
That complication class alone makes this a coin flip, basically.
Way, waaay beyond BBL, which is already dubbed one of the most dangerous cosmetic procedures with the highest death toll.
And on whom are BrazilianButtLifts mostly done? Again, women. Insecure ones with body image issues...
