How long do you have to wait after a BBL to get a round two BBL?

You need to wait some time for the initial surgical inflammation to subside. In my practice I wait 3 or more moths before performing a second BBL and have found this period to be satisfactory.

Typically, 3 months would allow for the swelling to subside and fat resorption to take place, as regular liposuction may eliminate up to 50% of your fat deposits. In order to maintain fat viability, VASER liposuction could be performed, allowing up to 90% viability.If you are a good candidate for a Brazilian Butt Lift (BBL), the optimal outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. These three processes have demonstrated over 95% fat graft take. This means that your results will be stable as long as you maintain your weight. As an official VASER trainer, I am routinely referred unhappy BBL patients. One of the most common reasons for disgruntled BBL patients is that patients are not able to accurately communicate their desired buttocks goals to their surgeons.  A buttocks assessment tool can be an invaluable tool to communicate to your surgeon the exact buttocks size and shape you are desiring. A Skype or Facetime consultation with a BBL specialist can help you get an accurate recommendation and pricing.
