My butt looks small again! Will my BBL change throughout the months with getting bigger? Or is this the size I am going to be?

The results immediately following surgery will be the largest due to swelling and lack of fat resorption.  The buttocks will continue to decrease in size for the first few weeks.   I have observed that between 4 and 6 weeks the buttocks tend to stabilize in volume.  Usually by 3 months, the swelling is minimal and totally resolved by 6 months.  
Follow your PS's post-operative instructions to achieve optimum results.

Dear yayalee3,
most patients lose 30-50% of transferred fat. I understand your concern and it is quite normal to be concerned about the outcome following a BBL surgery. However, you are still in the very early stages of the healing process.
Your will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues are still swollen. Once the swelling subsides  you will be able to see the final result of your surgery.

On average 1 month after surgery is too early to the make a decision on ones final result, usually 3-6 months is required to consider if an area requires a revision or such up correction. Meaning your recovery and final result depends on the amount of fat removed from liposuction, the areas liposuctioned, and the amount of fat transferred to your buttock.

Hello dear!!
Thanks for the question and provided information as well.
After a BBL, only about 70-50% of the transferred fat cells will survive, so it is normal to see a minor reduction in your buttocks. If you have any concerns, I suggest you to follow up close with your plastic surgeon.
Good luck :)

In my patients the buttocks shrinks as the swelling goes down and the 30% of fat cells die in the first three weeks.  I find it a rare that the buttocks could be the same size aftereffect transfer as it was before.  You've also got a remember that your waist is swollen too and that makes the buttocks look smaller.  It takes about three months for 90% of the swelling to go away so your buttocks will definitely look bigger and better as you heal. I've had several patients who say the buttocks looks too small at three weeks and it's too big six months.

4 weeks post-op is still too soon to observe the final outcome of the operation, but no, you should not expect your buttocks to increase in size as the months go by. You need to give it the full 3 months to heal, but if you're still not pleased with the results by that time, you may be a candidate for a BBL revision.If you are a candidate for a Brazilian Butt Lift (BBL) revision, 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.

it's unfortunate you're not happy with your BBL at results. There's not much you can do at this point other than to follow up with your provider and share how you feel about the results.  Your bottom may continue to shrink a very small amount but your results are becoming closer to final. He will not regain any volume with time.  Best, Mats Hagstrom MD 

Congratulationson your recent procedure...The procedure of liposuction is an"insult" to the soft tissues, resulting in swelling which willinitially totally obscure the operative result. Thepurpose of a compression garment is to prevent bleeding and to controlswelling. We usually recommend its use for the first 4-6 weeks after theprocedure. 60-80%of the swelling should subside within the first 6 weeks, with the remainderslowly subsiding over 6-12 months. The initial fullness you experienced was due to the presence of inflammatory swelling. As it subsides, the result becomes apparent. It is important to know how much fat was injected into the buttocks during the procedure. After 6 months (to allow for subsidence of swelling and the hypervascularity of healing), you may consider a secondary procedure. 15% of cosmetic procedures require a secondary touchup.Continuefollowup care with your plastic surgeon.Best wishes...
