Why does my makeup make me look like a ghost? The main reason why your foundation looks grey on your skin is because of the foundation shade you are using. If you pick a shade that is much lighter than your skin tone without having the same undertone, this will make your skin look dull and grey after application.
Why do I look weird with concealer on? You’re using the wrong shade
If you are using a shade that is too light, you’ll literally be shining a spotlight on your under eye area, wrinkles and all. If you are using a shade that is too dark, it will just look awkward and out of place. The fix: I like to use just 1 shade lighter at most.
Should your concealer be the same shade as foundation? “You can’t have a concealer that’s too light,” she said, adding that women should choose concealer that’s one to two shades lighter than the color of their foundation.
Is concealer supposed to be lighter than your skin tone? While under-eye concealer should be lighter than your natural skin tone (or red-orange if you’re colour-correcting), you want your all-over concealer to match your skin colour as closely as possible.
