I don't think so, but as the saying goes, never say never in medicine.
The cottage cheese appearance happens when connective tissue compartments that hold fat pull in skin that is hanging.
Up to now in over 5 years of doing Brazilian Butt lift, it hasn't happened to me. There is a reason I think it is not likely to happen, and it is that I inject fat into the lateral column of the buttock, and that tends to keep the buttock elevated. Less hanging skin, less cottage cheese appearance.
