Concealer (color corrector) is a type of make-up used to cover dark circles or any pimples in your skin. It is mostly used for the face and it is a type of liquid that blends in with the skin tone. This product is mainly used by women but use among men is increasing. There are different type of concealer shades, from light to dark. The colors are intended to look like your natural skin color and even though these are the most common, the use of primary and secondary colors are also used for festivals, halloween and other especial events. Many girls use it daily because of the fact that it is not noticeable. The three concealers that we used were Mayballine, Mac and Mary Kay. The best one of this three was Mayballine, this product was the winner for all of the tests that we did.
