The term Brazilian butt lift is used when buttocks are augmented with autologous fat injection harvested at the same session with liposuction.

Each butt lift technique results in a different scar. For great relaxation, especially after a lot of weight loss, the scar is hidden inside the underwear, and is perpendicular to the longitudinal axis of the torso (it can be part of the rounder abdominoplasty). In cases where not much skin and subcutaneous fat removal is required, the scar is hidden between the buttocks (interglottic groove). There are also cases where only the lower part of the skin of the buttocks can be removed, the so-called banana removal.

In cases where we have a small loss of muscle mass or slight relaxation, we can correct the fall of the buttocks by placing implants (prostheses of silicone, fat or hyaluronic – Macrolane), without removing the skin. In all other cases, we combine the augmentation of the buttocks with the placement of the implants, when the person concerned wants more volume in the buttocks. I strongly advise againt this combination and feel more comfortable with autologous fat grafting as there are less complications. 

Skin sagging is not corrected with exercise. In other words, the skin does not work out. The skin may be attached to the underlying muscular system, which may help to tighten it a little, but it is not enough.

Side effects are usually limited to healing problems when it comes to extensive incisions, which are easily treated. Other possible side effects are hematoma, inflammation, etc.

The results in butt lift are permanent, provided the body weight is kept constant.
