Which of the following best defines the role of a stipple sponge?

The role of a stipple sponge is best defined by its ability to create textured effects on the skin. This type of sponge is specifically designed with a unique surface that allows for the application of makeup in a way that provides depth and dimension, making it ideal for techniques that require a more artistic touch, such as stippling, which involves dabbing the sponge onto the skin to produce a spotted or small-patch effect. This technique can enhance the natural contours of the face and is often employed in special effects makeup, stage makeup, or to achieve a more dynamic look in everyday applications.

While a stipple sponge could be used in conjunction with other makeup products, its primary function isn't to apply powder, blend foundation, or specifically add color to lips, as those tasks are typically performed using tools better suited for those effects, such as brushes or different types of sponges designed for smooth application.
