When it comes to applying makeup, we've all got our little habits. Some of us religiously start with the foundation, while others begin with eyeshadow. Maybe you use your hands to blend, or are strictly in the "Beauty Blender" camp. Whatever your flow, there's one thing that most of us have in common - opening our mouths when we apply mascara. When you think about your friends putting on their makeup, the chances are that you'll recall that close-up to the mirror, wide-jawed expression. It's one of those things that happens so often that we just accept it as part of our daily lives, but now one expert has dished the dirt to Popsugar on exactly why we do it.
According to body language expert Blanca Cobb, "mascara mouth" is simply a subconscious action that most of us don't even notice. Cobb admits that no one really knows for sure why we keep our mouths open when fixing up our luscious lashes, but it's most likely down to nerves cross-firing. As we try and keep our eyelids as still as possible to avoid a nasty jab in the peeper with a jagged mascara wand, we're battling to control our facial muscles. Two sets of different nerves are responsible for the movement of our eyelids and mouth, but they're located in the same area. Hence, when we aim to control one we're most likely causing the other to fire, leading to our lips parting. Isn't science a wonderful thing?
Although it's not a steadfast law - you can put mascara on with a closed mouth - so many of us are used to doing it instinctively that it's unlikely we'll ever unlearn the habit. Cobb says that this is "reinforced behavior". Our bodies have done it for so long that it feels like it works, and changing the habit now would feel plain wrong. In short, if it ain't broke, why fix it?
Keep that eye on the ball and that jaw to the floor ladies, or, try to keep your mouth shut next time you coat your lashes and see if it's really possible.
