Applying foundation with a brush offers excellent spreadability, making it easy to achieve a smooth skin texture. Additionally, since it allows for seamless application even over uneven skin texture and pores, using a brush is recommended for those who need pore coverage. However, a disadvantage is that you cannot carry a brush around all the time, making touch-ups difficult when out and about. Furthermore, just like a puff, it is prone to contamination, so you must take care of it.
