Q: How do I find a concealer that works with my skin tone?
A: Finding the right concealer has long been one of the great mysteries of the beauty universe: Like theories about dark matter, theories about concealer have been legion (if not quite as mind-blowing). Is the perfect concealer lighter than your complexion? A quarter shade darker? Do you test it on the pad of your thumb or around your nose? You'll be relieved to know that if you have about an hour (including travel time) and a hand mirror, you can find exactly what you need at a department store. It's deceptively simple. But first you must find the right foundation shade, says makeup artist Bobbi Brown. Take your freshly washed, unmade-up face to the store and swipe several shades of foundation just above your jawline. Now slip out to the sidewalk with your mirror and, in the natural (probably unflattering) light of day, see which swipe disappears into your skin. That's the foundation to call your own. Head back into the store for your concealer, which should be just one shade lighter than the foundation.
Keep in mind: Dusting the concealer with a sheer, translucent powder will set it and help blend it into your complexion.
