Boost brows with this MAC Pro Brow whipped mousse, pairing an air-whipped formula with a precision micro-styling brush to build natural-looking color and fuller, more defined brows with ease. Sunflower seed and carnauba waxes help create soft volume and flexible 24-hour hold, while the waterproof, clump-free formula resists smudging, flaking and fading for polished all-day wear.
