Mascara + Air = Bacteria

Avid Bella readers may recall that mascara is the first makeup to spoil. But my ever curious (and frugal) side wondered . . . why does it have to be my pricey DiorShow that gets the curse of the short shelf life?! Since the idea of bacteria near my eye doesn't apply to the reasonable realist in me, I figured if I knew why it went bad, I'd better understand when to toss.

Turns out mascara is more prone to the harboring of bacteria because of the way it's used – first you pull the wand out, then you put it back in. Think about those of you who reapply, or never leave the house without at least three coats. (You know who you are.) Each time you do that air gets into the tube.

If I haven't scared you off yet, find out what happens next

.

Not only can "pumping" mascara cause it to dry out faster, that addition of air creates a veritable breeding ground. Each application introduces bacteria to the wand and pushes it into the tube. As you do so, both the (potential) bacteria and air inside are increased and trapped, and thus begins the reproduction. Gross already but then the relatively humid, closed environment becomes even more susceptible to bacterial growth (like closed toothbrush containers).

When pulling out the wand, make sure to do a twisting not pumping motion to minimize the trapped air for as long as possible. The good news is that mascara includes an antibacterial agent (commonly PVP or VP) to stave off this infection and keep you safe for a few months . . . after that, you may be sorry.

I tend to run out of mascara before the recommended three month mark. If I've been getting every last dab out of the tube I'll ditch it as soon as it starts to get gluggy.

That's why I would never spend a shit ton of money on mascara. That definitely goes on the list of make-up items NOT to splurge on. Sorry Dior show. I love you, but I love my wallet more.

Pumping the wand is definitely bad--I learned that a long time ago. And I'm pretty good about tossing my mascara after the recommended 3 months. I don't want any kind of eye infection, that's for sure.

I always twist instead of pump, and I wash the wand off before I put it back in the tube, especially with the more expensive ones! lol

Eww... I hardly ever wear mascara though, so I'm not too worried. I never "pump" the wand when I do though, always twist it out.

This is something I never would have thought of. I usually pump the wand, but twisting, it is! Here's a great article about "When Good Makeup Goes Bad," too. http://www.beautyschoolsdirectory.com/blog/articles/when-good-makeup-goes-bad/
