While using liquid foundation, nothing works better than a blending sponge. It is the perfect thing to airbrush a liquid foundation on your face seamlessly. The round and smooth sponge helps even out the foundation on the face without any lines.
One must certainly keep a concealer brush handy. Without this, your makeup can never be on point. A concealer brush is usually pointy as it needs to even out the skin tone of specific areas such as under eyes and the chin area. This applicator only helps give the right finish to your face.
