What is Mascara Mouth?

Mascara mouth, also referred to as “mascara drool,” is a phenomenon in which the wearer of mascara opens their mouth to apply it around their eyes.

It’s a common habit of many people who wear makeup, and it can be quite alarming if you don’t know why they’re doing this. Please know that there is nothing to be worried about. It’s a reflex that your body is used to doing because most of us breathe through our mouths.


Is it Normal?

Yes, this is normal!* It’s a habit that many people have. Don’t worry if you open your mouth while putting on mascara. You’re not alone. Just put on your mascara as you normally do.

Unless you are getting the mascara residue into your mouth, we promise it’s 100% normal.


Why Does it Happen?

The easiest answer is that it’s a habit. We’ve done it for so long and so often that our bodies do it automatically. If it bothers you that your mouth opens when putting on mascara, you can train yourself not to do so.


Can You Stop it?
