Natural makeup brushes are made of animal hair (often sable, squirrel or goat) and, for this reason, tend to be more expensive than synthetic brushes.
Do expensive makeup brushes make a difference?
Inexpensive makeup products and accessories can affect your overall makeup. The products do not spread uniformly across your face, resulting in clump formation. But expensive makeup brushes ensure a seamless application and an airbrushed look. As a result, your makeup lasts longer and looks better.
