MAC Stack Mascara Superstack Micro Brush — Buildable Volume & Length, 0.41 oz

MAC Stack Mascara Superstack Micro Brush is a continuously buildable mascara that layers volume and length without heavy clumps.

This Superstack formula from MAC is designed to be applied in successive coats so you can dial in dramatic volume and extended length while keeping lashes defined. The larger Mega Brush reaches upper and longer lashes, and the micro-bristle design separates each hair as you add layers. The lightweight cream formula stacks, rather than balls up, so you can intensify coverage throughout the day or for evening looks.

How does the micro brush help create more dramatic lashes?

The micro brush combines larger overall shape with fine bristles to coat lashes evenly and lift from root to tip. It balances product pickup with precise application so each lash gets separated rather than clumped together.

• Micro-bristle pattern combs through lashes for separation.
• Mega brush size deposits volume on longer lashes and upper outer corners.
• Even product distribution prevents heavy buildup at the base.

Can I layer this mascara without it flaking or clumping?

Yes — the Superstack formula is made to stack in multiple coats while staying smooth and clump-resistant. Apply additional layers before the formula fully dries to build intensity, or let each coat set for more controlled volume.

• Buildable texture allows tiny increments of volume per coat.
• Clump-resistant formulation keeps lash separation consistent.
• Suitable for both subtle day looks and bold evening styles.

How long does one 0.41 oz tube last and how should I apply it?

Longevity depends on usage frequency and how many coats you apply; many users find a 0.41 oz tube lasts multiple months with regular use. For best results, start at the root and wiggle the brush upward, layering until you reach your desired fullness.

• Root-to-tip wiggling lifts and curls while adding volume.
• Apply 1–3 coats for daytime, 3+ coats for dramatic looks.
• Replace after three months of daily use for hygiene and performance.

Who is this for: The MAC Superstack Micro Brush Mascara is for anyone wanting a customizable lash look—those with longer or upper lashes who need better brush coverage, makeup lovers who enjoy layering without flaking, and anyone aiming to move from natural definition to full glamour with a single, easy-to-control product. It’s especially useful for users who prefer to build intensity gradually and value a brush that reaches every lash.
