I have dark circles under my eyes... its genetic so theres not much I can do about it but hide it. Also it's kind of a sunken-in effect. So any tips for that would be great too. But yeah, in your experience what is the best undereye concealer? I wont spend too much on it.. tops maybe $20-25.

for five dollars, try maybelline coverstick. use the yellow correcting color first, then follow that up with a color that matches your skin tone. it blends really well, covers quite nicely, and melts into your skin. it doesn't feel cakey at all!
