Worried about hollow under-eyes? What are the care methods after revision surgery?

I have a question for those considering revision surgery due to hollow under-eyes. I would like to know what specific precautions should be taken during the recovery period. In addition to pain management, are there any behaviors to avoid in daily life or skincare methods you would recommend? I would also like to hear effective tips for reducing swelling or advice from those with experience. Your valuable opinions would be of great help.
