What are the precautions after under-eye fat repositioning?

I have a question for those considering under-eye fat repositioning. What precautions should I take after the surgery? I would appreciate it if you could let me know if there are any specific activities or dietary restrictions I should follow, especially during the recovery period. I would also like to hear recommendations for effective methods to alleviate pain and swelling. Additionally, I would like to hear opinions on the actual results and effectiveness of this procedure through the experiences of others.
