In collaboration with professional makeup artist Katie Jane Hughes, the Spectrum Collections KJH Number 23 Brush is a multi-purpose tool, perfect for beauty beginners and MUA pros. Featuring a small, angled end and a spoolie, this precision brush is ideal for shaping and defining the brows or lining the eyes. Once you’ve filled in and created your hair-like strokes, go over the brows with the spoolie to soften.
