Applying this type of product with your fingers or a regular sponge tends to leave uneven patches, especially on larger areas like the full leg. The included kabuki brush has a wide oval head with dense, charcoal-infused bristles that press the product into the skin and blend it evenly in a single pass. It also keeps your hands clean throughout the process, which matters when you are covering an area as large as both legs. Together, the cream and brush give a consistent, natural finish that would be harder to achieve with either product used on its own.
