Achieve effortlessly bold and voluminous brows with MAC Eye Brows Big Boost Fibre Gel (4.1g), in the rich Brunette shade. This innovative gel expertly combines a buildable formula with tiny, lengthening microfibres to create naturally fuller, more defined brows – perfect for achieving that coveted model-off-duty look.

Unlike traditional brow gels, MAC's Big Boost Fibre Gel doesn't just set your brows in place; it actively adds volume and dimension. The lightweight texture feels comfortable all day, preventing stiffness or a heavy, unnatural appearance. The microfibres seamlessly cling to each brow hair, extending their length and creating a beautifully sculpted, yet natural, finish.

Whether you prefer a subtle enhancement or a dramatic, statement brow, Big Boost offers ultimate customisation. Simply apply with the precision applicator for controlled shaping and layering, building intensity to your desired level. Perfect for all brow types, from sparse to naturally thick, this gel ensures flawlessly groomed brows that last.

This versatile product is a must-have for your makeup bag, offering long-lasting hold and a naturally enhanced look. Experience the transformative power of MAC's Big Boost Fibre Gel and say goodbye to thin, sparse brows.

Key Features:

  • Buildable volume and definition.
  • Microfibres for natural-looking fullness.
