Why don't I have any projection after my BBL! 1 week post-op. (Photos)

At one week post op, it is way too early to see the final results of your liposuction surgery and fat transfer to your buttocks. 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.

Dear nununia,I understand that you are worried about the results of your surgery. However, you are still in the early
phase of the recovery period. Please do allow some time for the healing process
to occur and swelling to resolve. If after a few months, you are not satisfied with the appearance, you can visit your plastic surgeon and discuss your concerns.Daniel Barrett, MD, MHA, MS

It is too soon to say. You are likely swollen over the liposuction regions and this can contribute to your present shape.
