How can I manage the increasingly severe under-eye bags?

As time goes by, the bags under my eyes keep getting sunken and sagging...
It is more noticeable when viewed up close, especially in bright light.
I originally had wrinkles and dark circles around my eyes, so I felt like the symptoms were getting worse as the wrinkles, dark circles, sunkenness, and sagging all came together.

I used to just care about dark circles, but now they're fading and I look more tired, and my impression has definitely changed...

When I take a picture, only the area under my eyes is visible.

I've heard that a lot of people are getting under-eye surgery these days. Has anyone had it done?
There are so many different treatments, so where should I start and how should I find out?
I have a lot of questions about the maintenance period, pain, side effects, and whether the results will return after the procedure.
Besides the procedure, what other management tips would you recommend?
