MACStack Waterproof Mascara

MAC Cosmetics' MACStack Waterproof Mascara delivers buildable volume with a water-resistant finish and a smooth, creamy texture that layers without heavy clumping. Suitable for long wear and humid conditions, it's aimed at users seeking bold lashes that stay put. The formula works well for sensitive eyes and can be paired with lash primers; its waterproof nature makes it travel- and sweat-friendly.
