From Sephora, I like Make Up For Ever HD Invisible Concealer in #350, it's a great peach undertone that corrects the dark circles really well! It's also not dry, so it's great for the undereye area, it hydrates and looks really nice alone if you are around light-med skin tone. If you are fair-light you can try #320. You can also use it under a concealer and it doesn't cake. I just recommend setting it with a powder
I like it, but it's too light if u are around NC30, it makes the dark circles look ashy. It did look great under her concealer, I used honeycomb and it made my dark circles disappear
