I am looking for recommendations for an under eye concealer. I have dark circles (likely allergies as well as fatigue/pigmentation issues) and would like to cover them up, at least for some occasions. I usually do not use any foundation, preferring a sheer BB cream to even out some areas.

What do you all use, given that I would prefer it to work on bare skin. Is that even possible? I am a such a newbie And, while we're at it, can we find one that does not sink into my fine lines? I do use an under eye cream daily.
