M·A·CStack Volumizing Mascara FAQ
What is M·A·CStack Mascara?
A continuously buildable, clump-resistant mascara that lets you stack layer after layer for customizable volume and length—without weighing lashes down.
How should I apply M·A·CStack Mascara?
For oily skin and heavy concealer:
Start eye look with Prep + Prime 24Hr Extend Eye base, apply with fingers or 242S Brush to your eyelids
Wipe excess product from mascara brush
Brush from root to tip wiggling it on each lash
Apply another coat
Finish by misting face with Fix+ Stay Over
Important: don't pump wand into tube
To Boost Volume and Wear:
Apply False Lash Maximizer
Wipe excess product from mascara brush
Brush from root to tip wiggling it on each lash
Apply another coat
Important: don't pump wand into tube
Which brush should I choose: Mega or Micro?
Mega Brush: Best for instant, dramatic volume on longer or fuller lashes.
Micro Brush: Ideal for short, fine, or lower lashes—delivering ultra-precise definition without overload.
Does it clump or flake when I build layers?
The formula is designed for stackable, clump-resistant application and a clean, flake-resistant finish, even as you build multiple coats.
How does it feel and wear?
Lightweight and flexible from first swipe to last layer. The formula is long-wearing with smudge-resistant performance to keep your look fresh throughout the day.
How long does M·A·CStack Mascara last?
Expect 24-hour wear with buildable impact that stays put—whether you prefer a subtle lift or maximum volume.
Can I layer M·A·CStack Mascara over time without removing it first?
Yes. The formula is designed to be re-stackable—so you can refresh volume and lift as needed without starting over.
How do I remove it at the end of the day?
Use a gentle eye makeup remover. Oil-based or dual-phase formulas help break down mascara quickly while keeping the eye area comfortable.
