Are BBLs safe for muscular glutes?

BBLs can be safe for with muscular glutes as long as the procedure is performed by a highly skilled and experienced plastic surgeon. The primary concern with BBLs is ensuring that fat is not injected into the deep muscle layer, as this can increase the risk of complications such as fat embolism, pulmonary embolism, and death.
A knowledgeable surgeon will know how to avoid injecting fat into the muscle and will instead place it above the muscle in the superficial layer, where it can integrate properly without causing harm. It's important to choose a surgeon who understands gluteal anatomy and has experience with BBLs.

BBL is safe, even if you have muscular glutes. The important thing to consider is whether or not your surgeon is board-certified, experienced, and knowledgeable about gluteal anatomy so that they can avoid injecting fat into the deep plane of the muscle, which could lead to a fat embolism that would put the patient at risk of death. In general, when performed by a BBL specialist, with fat injection performed above the muscle, this procedure is tolerated very well and is safe.
