M.A.C Mascara M.A.CStack Mega Brush Chestnut Stack 12ml

M·A·CStack Mega Brush Chestnut Stack Mascara is a volumising, lengthening formula designed for those who like to build their lash look from subtle definition to bold impact. The rich chestnut brown shade offers a softer alternative to classic black, flattering a wide range of eye colours and ideal for everyday wear or a more understated evening look. The clump‑resistant texture works to separate and coat each lash, helping lashes appear longer, fuller and more lifted while still feeling lightweight and comfortable throughout the day.

This mascara is designed to be layered, so you can customise the effect to suit your mood, from a single coat for natural enhancement to multiple coats for more dramatic volume. The Mega Brush is tailored for upper and longer lashes, helping to fan them out and catch each lash from root to tip. Use it as the finishing step in your eye make‑up routine after eyeshadow and liner to frame the eyes and complete your look.

How to use
How to Use:
Start with clean, dry lashes and remove any excess oil or residue. Wipe any excess product from the wand. Holding the Mega Brush horizontally, press it into the base of the upper lashes and sweep through to the tips, wiggling slightly to coat each lash. Apply additional coats while the formula is still slightly damp, building volume and length until you reach your desired look.

Frequency:
Use as needed, according to the product instructions and your make‑up routine.

Application Technique:
Focus the brush at the roots to help create lift, then pull through to the ends for length and separation. Use the tip of the brush to reach corner lashes and any shorter lashes that need extra definition.

Best Practices:
Apply after completing eye shadow and liner. Allow each coat to set briefly before adding more. Remove mascara thoroughly at the end of the day with an appropriate eye make‑up remover to help keep lashes in good condition.

Safety Tips:
Avoid getting the product directly into the eyes. If irritation occurs, discontinue use. Use externally only and keep out of reach of children. Follow any additional guidance on the packaging.
