A: Step 1: Choose the brush material When choosing your makeup brushes, it's important to factor in the material the brushes are made of. The makeup formulas you use will help you determine whether to choose natural, real hair or synthetic, fake hair usually made of acrylic or plastic.
                Natural brushes are better for dry products like blush and eyeshadow and synthetic brushes are best suited for cream or liquid products like concealer or foundation because they soak up less product than natural hair.

    Step 2: Choose the brush size and firmness So you know what material you want, and now it's time to find a brush that feels good on your face. Makeup brushes are pricey, but are a worthwhile investment that can last a long time, so choose brushes that are comfortable on your face and non-irritating.

A: Do this by cleaning, sanitizing and properly drying them regularly. Here's how:
    Use a brush cleaner once a week Spray it "onto a Kleenex and sweep the brush back and forth to remove the makeup."
     For a deeper clean, wash your brushes with shampoo. "Add a drop of shampoo to a cup half full of warm water. Swirl the brushes around and then thoroughly rinse. Then "let them dry flat on a towel," because "if they dry upright, the water will drain into the metal casing and break down the glue causing bristle loss."
