Our verdict

A buildable black mascara with a big brush for stacking volume and length on upper lashes. The large wand makes small lower lashes harder to coat cleanly.

Overview

Stacking coat after coat, MAC Macstack Superstack builds volume and length without clumping. Its bigger brush coats longer upper lashes in one pass, and the formula is waterproof and smudge-proof.

Layering without clumps is what lets it go from natural to dramatic in one tube. The oversized brush suits long upper lashes but is clumsy on short ones.

Who it's for

Evening looks and long lashes that can carry volume suit this mascara. People with short lashes or who want a quick natural coat may find the brush unwieldy.

Performance notes

A clump-resistant formula dries in thin layers, which is what allows coat after coat to stack without gluing lashes together. The big brush loads more product per pass, so length and volume build fast.
