The first one the consultant suggested was the NARS Radiant Creamy Concealer in Custard. It perfectly masked my dark circles, but at $28 a tube, I had to ask for something cheaper. She directed me to the Sephora Collection, which I usually stay away from, because sometimes I feel like it might be cheap. However, the 8 HR Wear Perfect Cover Concealer in 22 Light Natural is an exact match. I swatched both in the store and walked arounf trying to match them with another (reasonably priced) product and just couldn't. Nothing had that yellow tint that I needed. So I settled and was super pleased with what I got, especially for $15.
They don't look alike in these pictures, but, all the more reason to go in and spend some time
Lesson: if the makeup the consultant suggests is too much, she'll find you a cheaper option that matches exactly.
