How do you use a concealer? Well, having a concealer in your makeup bag is like having a little bit of magic always on hand. You can hide dark under-eye circles from too many late nights, even out skin tone or hide the inconvenient blemish that may have popped up at precisely the wrong time!

Concealer is usually applied after foundation and should be one or two shades lighter than your foundation colour.  If you're not sure, its best to go lighter rather than darker.
