Designed with a dual technology that has never been seen before, the skin2skin foundation brush uses varying length bristles that are tightly layered in a swirl pattern to effortlessly and instantaneously blend your foundation. The brush is thicker at the bottom and thinner at the top, allowing the fibers to reach every curve of the face. Mimicking skin to skin application, the foundation brush covers pores and does not drag across skin. This brush is free of animal hair and is completely vegan.
