The popular photosharing app Instagram has played host to many internet trends in recent years. Do you remember breading, planking, or the infamous Harlem shuffle?! Okay, so perhaps we didn’t really need to be reminded of that last one.

Now, the latest trend making waves on Instagram involves women posting pictures of themselves with makeup on one side of their face and no makeup on the other and asking which side looks better.

The trend is taking Instagram by storm, and, because it is such an image-based trend, it is unsurprising that the photosharing app was the platform of choice for participants.

However, this is not the first time a trend like this has been popular. A similar trend swept Twitter a few years ago when users were asked to post a picture of what they looked like when they first got up in the morning.

The photos were captioned #wokeuplikethis and generally showed people disheveled and without makeup. Several celebrities got in on that trend too, and some revealed themselves publicly without makeup on for the first time.
