I'm worried about hollowness under my eyes. Has anyone had a similar experience?

I am a woman in my 20s considering surgery or a procedure because my under-eye hollowness has worsened. I have spoken to friends, and they say the satisfaction rate after surgery is high. However, I am curious about the recovery period and pain levels for those who have actually undergone the procedure. I would also like to hear how long it took to return to daily life after the procedure. I would be very grateful if you could let me know if there are any hospitals you would recommend or any precautions I should take.
