You can sit on your BBL pillow for as long as you feel comfortable. There is no specific time limit, but it is recommended to not sit for more than 30 minutes at a time. Taking regular breaks and moving around is important to avoid putting too much pressure on your buttocks and compromising the results of your Brazilian Butt Lift surgery. Make sure to follow the instructions provided by your surgeon for post-surgery care and use the BBL pillow as directed. Sitting on the BBL pillow helps distribute weight evenly and reduces pressure on the buttocks, aiding in the healing process. Remember to consult with your surgeon if you have any concerns or questions about using the BBL pillow during your recovery period.
