Why does mascara flake during the day?
Flaking mascara is usually old product, over-application, or a dry formula losing its flexibility once set.
Short answer
Flaking is tiny dried flecks of mascara breaking off the lashes, usually a few hours after application. It almost always comes down to the product being past its useful life, applied too heavily, or built from a formula that dries brittle rather than flexible.
Why it happens
Mascara is a suspension of pigment and waxes in a liquid carrier that thickens as it's exposed to air every time the tube is opened. Once it thickens past its intended consistency, it goes on drier and sets less flexibly, which means it's more likely to crack and flake off lashes as they move rather than staying put. Layering on too much product at once has the same effect, since the outer layer dries before the inner layer has fully set.
How to prevent or fix it
- Replace mascara every three months. It's the shortest-lived product in most routines because the tube is opened and exposed to air constantly; flaking is often simply the sign it's expired.
- Don't pump the wand in the tube. Pumping pushes air in and dries the formula out faster - twist the wand instead when loading it.
- Apply thin coats and let each one set. Two thin layers, with a few seconds between them, flakes less than one thick layer.
- Curl before applying, not after. Curling lashes first, then applying mascara, holds the curl better and avoids applying pressure onto already-dried product. See Eyelash Curler.
- Consider a tubing formula if it persists. Instead of coating lashes in pigment and wax the way traditional mascara does, tubing formulas wrap each lash in a flexible polymer sleeve that holds together rather than drying brittle, which makes them noticeably more flake-resistant. They remove differently too - with warm water rather than an oil-based remover.
