Which makeup tool is typically used to apply foundation?

The makeup sponge is specifically designed for the application of foundation due to its unique texture and shape. It is used to blend foundation into the skin for a smooth, seamless finish. The sponge can absorb some moisture, allowing for a more natural look, and its versatility allows for both stippling and blending techniques, making it an essential tool for creating an even complexion.

In contrast, other tools like the eyeshadow brush, lip brush, and eyeliner brush are designed for specific purposes related to their respective makeup applications. The eyeshadow brush is tailored for applying and blending eyeshadow, while the lip brush is used for applying lipstick or lip gloss with precision. The eyeliner brush is meant for applying gel or cream eyeliner. Each of these brushes has a design that caters to the particular areas of the face they are meant to address, making them less suited for applying foundation effectively.
