SYNTHETICSYNTHETIC
Synthetic makeup brushes have bristles made up of man-made materials, like nylon or taklon, and are typically machine-made. These types of brushes have a sleek finish that pairs well with cream products and they often become rigid and stiff with use.

NATURALNATURAL
Makeup brushes with natural bristles are made from natural sources, like goat, squirrel, sable, and fox hair or fur. They are usually hand-made, have a more porous finish, soften with use, and pair well with powder products.
