Gym-proof your lashes

BareMinerals Locked & Coated Waterproof Lash Topcoat

This invisible topcoat is perfect for working out. It instantly makes mascara waterproof for lasting and locked wear. The formula is made with black diamond, amethyst, sapphire, and ruby, and the ultra fine bristles of the moulded brush evenly coat each lash without altering your mascara application. This mineral-rich finishing product won’t smudge, clump or flake, and just one coat is enough to seal the deal. You can also use it to keep eyebrows in place.
