A concealer is a cosmetic product designed to camouflage pimples, small skin imperfections such as rosacea, pigmentation spots and dark circles.
There are concealers in liquid and solid form, at Parfas we only sell the fixed version, namely a compact cream. The difference with a foundation is that a concealer is usually stronger colored, and is used for smaller surfaces. The concealer is usually applied for the foundation, but can also only be used if you do not use foundation. The first concealer was available in 1938.
The concealers of Youngblood exist in different colors. Some colors imitate the natural skin colors, these are mainly used against pimples and other imperfections. Other colors contrast with the unevenness they try to hide. For example, a pink helps against dark circles, and yellow or orange against bruises.

For the circles under the eyes, it is best to use only concealer and no foundation.
If you want to get rid of spots you can do this both before and after do the foundation, that is just where you prefer.
If you put it in mind, keep in mind that you will not wipe the concealer away when you apply the foundation.
