Rimmel Glam'Eyes Day 2 Night Mascara in Black offers a customizable lash look with its innovative dual-action brush. The mascara features two brush settings: one side is designed for defining and lengthening lashes for a natural, day-time look, while the other side offers volume for a more dramatic, night-time effect. The black shade provides bold, defined lashes that last all day without clumping or flaking. The versatile formula allows you to build your desired look, whether you want subtle, separated lashes or thick, voluminous lashes. With its long-lasting, smudge-proof formula, this mascara is the perfect choice for both day and night occasions.
