What are the essential post-liposuction care items?

I have a question for those considering liposuction. What is the most important aspect of post-operative care? In particular, I am curious about the specific precautions regarding diet and exercise for each body part during the recovery period. I would appreciate it if you could share what care methods you personally found effective, or if you had any tips that helped alleviate pain or swelling. I look forward to hearing about the changes one can expect after surgery and opinions from those who have experienced it.
