It should always linger in your head that the best make up is obtained by using the best tools, and this implies that for you to have a successful application of facial make up, you will need a reliable concealer brush.
The benefit of using a concealer brush to apply make up on your face rather than your hands is that, your hands may at times have some traces of oils that may tamper with the makeup blending, hence distorting your look.
A good concealer brush should have the following traits:
the brush should be soft, tapered and lightly pointed, this will allow a precise application of concealer which will extend to the inner cornea of one's eye; the best concealer brush is one that is made of nylon fibers, since they feel smooth and promote concealer application; and the concealer brush shape should be in such a way that you can use the flat side for larger areas.
You should always consider purchasing a concealer brush that is multi-purpose, meaning it should be compatible with both creamy and powder make up.
