How Firm Will Butt Be After Brazilian Butt Lift?

This depends on several factors such as:

Skin laxity
Volume of fat transferred
Dermal retaining ligaments
Viability of transferred fat

If you have loose skin and modest amounts of fat are transferred with only partial viability, it is likely you buttock will remain loose.
If, however, your skin is densely attached to the buttock muscles and large amounts of fat are transferred that successfully survives, it is possible you will have a relatively firm buttock.

A good candidate has enough fat available for transfer in the procedure. The amount of fat that can be transferred in a BBL depends on how much fat the patient has to harvest and the amount of space there is to move the fat into. It is recommended for the patient to have a BMI of 30 or less. If you are too thin, a Brazilian Butt Lift may not be possible.

Hi there-
The density of the tissues and the tightness/thickness of the skin is what will largely determine the feel of the butt after Brazilian Butt Lift, but in general, it does make sense that when you add filler (in the form of your fat) to the butt, it does plump up the skin and tissues, making the skin look more firm and the butt feel more youthful. This, of course is part of the appeal of the surgery... the butt looks and feels younger and better, and it is a permanent improvement!
