What kind of care is needed after liposuction surgery?

I have a question for those considering liposuction. What is the most important aspect of care during the recovery period? In particular, I assume the necessary care methods vary depending on the area treated. I would be very grateful if you could share how you managed swelling and pain, and if you had any experiences that were especially helpful during recovery. I would also like to hear information regarding pre-operative preparations and post-operative care tips!
