Cover up is a more common word and it is used to make someone's skin look flawless.

When used excessively, it can make your face look like a shiny orange orb. Whenever you can tell that someone is wearing foundation, they are wearing too much. Sometimes when not rubbed in correctly, over-applied, or the person in question has applied the wrong shade, they can get the mask effect. Foundation is used excessively by teenage girls, specifically bro ho's and girls who work in Abercrombie.

Girls wear it. Mostly worn with other forms of [makeup]. Can come in a cream, or as powder. Used to make skin seem perfect and fault-less. Applying too much makes them look like slutty fake barbie-dolls. But foundation is good if you want to hide freckles and blemishes.
