Can I sit on my BBL for 4 hrs? I am 6 weeks post op.

Thank you for your question! For my patients having a BBL procedure, I recommend they stay completely off of their buttocks for the first 10 days post surgery, then start using the BBL pillow for 3 additional weeks. At 6 weeks post op, there are no sitting restrictions and it is ok to sit directly on your buttocks. I recommend discussing specific post op instructions with your plastic surgeon. Best of luck!

The best answer will come from the PS who performed your BBL as he/she will be aware of your recovery.
I recommend that my patients minimize sitting, even with a pillow, for the first two weeks.  If they must sit, every 30 minutes or an hour, they should get up and stand for a few seconds to take the pressure off.   This reduces the chance for fat necrosis. I usually recommend about 6 weeks before sitting without a pillow. After 6 weeks the fat has revascularized, and they will have a very good idea of their final results.

Hello dear!!
Thanks for the question and provided information as well. 
I recommend my patients to use the booty pillow for 2-3 weeks, and after that, to limit the sitting time to 1 hr. and then stand up to release pressure. 
If you have any concerns, i suggest you to follow up close with your plastic surgeon.
Good luck :)
