What is the most important aspect of post-breast fat grafting care?

I have a question for those considering breast fat grafting. I am curious about the specific precautions to take during post-operative care. Aside from managing swelling and pain, I would like to hear advice from those with experience regarding specific care methods that were effective and how quickly they were able to return to their daily lives. Additionally, I would appreciate it if you could share any unexpected difficulties you encountered during the recovery process or any methods that were helpful.
