How much size increase with BBL? I am 37-33-38. (Photos)

Thank you for your question and pictures. It's hard to say an exact number of how much fat will be injected in a BBL, many factors can affect such as: the amount of fat obtained with liposuction, the quality of the fat, how much your buttocks can accept, etc. Sometimes up to 30% of the fat is reabsorbed, but it usually grows back after the swelling process is over. 

Hello lipoqueries,
It’s a pleasure to answer your questions! Every patient is unique, and every buttocks augmentation procedure (Brazilian Butt Lift (BBL) is customized to fit every single patient’s needs and expectations. In total, surgeons may safely remove up to 5 liters of fat (4 liters maximum in states such as New York and Florida) during VASER liposuction while carefully sculpturing the patient’s body to ensure optimal aesthetics. After the purification process, only 500cc to 1500cc of that fat will be injected into each butt cheek. A highly skilled and experienced plastic surgeon will achieve around 65% to 85% survival rate of the fat cells, and the rest will be harmlessly reabsorbed by the body. Smoking and/or sitting or lying on the buttocks too soon after BBL surgery will result in volume loss due to the resorption of the newly transplanted fat cells. Best regards! Dr. De La Cruz.
