Lashes take on superb scale, structure and sweep with MAC's lightweight, whipped mascara that saturates from root to tip, now in a waterproof formula. Enhancing volume, extending length, creating curl and staying put to the extreme, these highly defined lashes are clump-resistant and non-smudging – and can now withstand moisture. Add unparalleled volume and drama to the eyelashes with MAC’s In Extreme Dimension Lash. The lengthening mascara boasts a whipped, lightweight formula that seeks to curl and lift the lashes with ease. Boasting a large, moulded brush, the mascara offers an optimal amount of product with each stroke, as the tip of the brush allows for precise application. The symmetrical bristles gently grab and coat each lash without clumping or smudging, promoting an amplified finish. Ophthalmologist tested. Suitable for contact lens wearers. Press the brush into lashes close to roots and "shimmy" it through lashes from root to tip. Repeat until desired effect is achieved.
