What are sponges primarily used for in makeup application?

Sponges are primarily used in makeup application for blending foundation, concealer, and powder. Their unique texture allows for a smooth and even application, which is essential for achieving a natural look. When using a sponge, the product can be distributed evenly over the skin, helping to create a flawless finish and minimize visible lines or streaks.

The sponge's ability to absorb some moisture also aids in the blending process, especially when dampened slightly before use. This helps to ensure that makeup products meld seamlessly into the skin, giving a more professional appearance. Additionally, sponges can be used to build coverage gradually, allowing for flexibility in makeup application according to the desired look.

While other options may involve different tools or techniques, sponges are specifically designed for blending, making them critical for achieving a well-blended makeup look. This establishes why using a sponge for blending foundation, concealer, and powder is considered its primary purpose in makeup application.
