Do you guys know some ways to get rid of dark circles and bags?

I can't think of anything that will get rid of them permanently, but concealer and foundation might help cover them up c:

Drink plenty of water, make sure you are getting at least 8 hours of sleep, try to have a consistent sleeping pattern (go to sleep at the same time each night), eat well, and then my secret.....put vaseline all around your eye area each night and wash your face in the morning with cold water, apply some moisturiser, then concealer if you need it.

That's what I do and it works!

just go to sleep, you probably have then because of your lack of rest, or stress.
