If you want even coverage when applying your makeup sponge. We have all seen that "mask look" on someone who failed to blend their foundation properly. It looks awful, but we are hesitant to approach them for fear of offending them. They have most likely failed to choose the proper foundation for their skin color and they probably used their fingertips to apply the foundation, which can spread bacteria. This can result in breakouts or inflame acne that already exists. When using a sponge, it is critical to wash it thoroughly with warm, soapy water and rinse it well between uses then allow it to air dry. To use a natural sponge, soften it up with warm water, then remove as much of the water as possible. Wrap it in a paper towel and squeeze it if necessary.
