MACStack Waterproof Mascara, Blackstack

As a mascara from MAC Cosmetics, MACStack Waterproof Mascara (Blackstack) delivers a buildable, volumizing formula with a dense, wet texture that coats lashes for long wear. The waterproof, smudge-resistant finish suits humid climates and active days. Ideal for those seeking dramatic lift and separation rather than a natural sheer look. Works well on short or sparse lashes needing structure and hold.
