A concealer or color corrector is a type of cosmetic that is used to mask dark circles, age spots, large pores, and other small blemishes visible on the skin. It is similar to foundation, but thicker and used to hide different pigments by blending the imperfection into the surrounding skin tone.
Both concealer and foundation are typically used to make skin appear more uniform in color. These two types of cosmetics differ in that concealers tend to be more heavily pigmented, though concealer and foundation are both available in a wide range of opacity. Concealer can be used alone or with foundation. It comes in different forms from liquid to powder. The first commercially available concealer was Max Factor’s Erace, launched in 1954. Camouflage makeup is a much heavier pigmented form of concealer. It is used to cover serious skin discolorations such as birthmarks, scars and vitiligo.
Concealer is available in a variety of shades. When picking a concealer, people tend to choose one or two shades lighter than their skin tone to better hide their blemishes and dark circles under the eye. Some colors are intended to look like a natural skin tone, while others are meant to cancel out the color of a particular type of blemish. Concealers with yellow undertones are used to hide dark circles. Green and blue can counteract red patches on the skin, such as those caused by pimples, broken veins, or rosacea. A purple-tinted concealer can make sallow complexions look brighter.
