No concealer will really "treat" dark undereye circles. In some cases, like if your circles are genetic, even skincare (i.e., eye creams and serums) can't do it. You can colour correct to diminish their look, though. Or use a concealer in a shade that's roughly the same as your skintone, which others have suggested. With that said, the concealer I'm using now for under the eyes is Glossier Stretch Concealer (I use Very Light 2). I'm in my mid-40s and I've found that this one gives me enough coverage and it has a dewy finish. (In my case I deal more with slight hollowness and thin skin than full-on dark circles.) After some time it will crease a little in my lines, but that's easily fixed.
