Most Helpful Girl
I'm worried that she's a MAC makeup artist and told you it should be darker. It definitely should be lighter. A big use of concealer is to cover up dark spots especially under your eyes. If you used a darker shade on the dark circles then that's just making it worse. Try to add a highlighting powder that is lighter and see how this works. MAC has the best highlighter powders in my opinion (Mineralize skinfish is my fav line to use). If you don't feel comfortable buying their products again then there's plenty of other brands that sell it. You really should stay away from drugstore brands though. You want a good quality powder that pops, drugstore brands typically don't and are hard to put on. Also you will need the right brush. This is definitely an important part. You want something like this link If the powder doesn't work then go back and explain to the manager what happened and that you're new to makeup. Maybe they can switch the color for you to the right one. MAC associates have always been nice and willing to help me out so hopefully the manager can fix the problem for you.
