Beauty sponges are needed to evenly apply the foundation, if you want to get a denser coverage. With the help of a beauty sponge, you literally "imprint" it into the skin, controlling the amount of applied product. Before applying foundation, wet the sponge with water and wring it out: the sponge will become softer and more pliable, and the foundation will lay down in a more even layer. The pointed end of the beauty sponge makes it easy to apply concealer under the eyes (egg shape). Triangular-shaped sponges are very convenient to apply and remove excess foundation on those areas of the face that are difficult to reach for a regular round sponge (zones near the nose and eyes). Sponges made of natural materials allow you to apply foundation very easily and thinly, so that it is almost invisible.
