Offering continuous, buildable volume, MAC presents the Stack Mascara, a breakthrough formula that resists clumping, flaking and smudging, layer after layer. Create customisable definition, levelling up your look from soft and natural, to bold and dramatic. The bespoke mega brush coats lashes from root to tip with 360-degree coverage, while proprietary Fibre Melt Technology helps to create a smudge-proof finish. With a weightless feel and up to 24-hour wear, the gravity-defying mascara creates the illusion of instant lift and length.
