The bristles are made from synthetic material and feel super soft. The brush is really dense, but it`s not too dense to the point where if feels stiff. The bristles are flexible and they glide onto my skin smoothly without tugging my skin. The size and the density make it great for applying setting powder all over the face and for applying bronzer to the body, neck and decollete.
