How to rid of under eye bags and dark circles?

I’ve been struggling with them for a while but as of recently for some reason they’ve become so much more prominent and showy. Not only that but I’m only 19.

I’ve tried getting more sleep, using ice cubes, taking iron supplements and a vitamin C serum to brighten it. But nothing seems to rid of them, and once again especially in bad lighting they are extremely prominent.

If anyone could give me long term reasonable and affordable tips on how I could rid of my eyebags/dark circles I’d really appreciate it. Things like serums/products that actually work and life style changes.
