Thanks for your question.It all depends on how much fat was grafted or placed in the buttocks. If a significant amount of fat was placed, it's going to feel firm initially and it can take 3 to 4 weeks to soften. Please always consult with a board certified plastic surgeon.Take care,Moises Salama M.D., Board Certified Plastic Surgeon
Often the buttock can feel quite firm from swelling initially. As you heal the swelling will subside and the buttock should feel more normal.
