The benefits may persist for many years if the application is done correctly, and the patient takes proper care of himself. Brazilian butt lifts are semi-permanent due to the semi-permanent nature of your fat. For better or worse, the effect is permanent after part of the fat that was injected has been reabsorbed by the body. However, this does not rule out the possibility that your hips may alter as a result of your dietary habits or the natural aging process over time. You should still keep a healthy lifestyle after the surgery. Although Brazilian Butt Lift has a positive effect on your lower body, it is in your hands to keep this effect lasting.
