Tarte shape tape!!!


Okay so I picked up tarte’s shape tape concealer a few days ago because it’s considered the holy grail of concealers, right? WELL. I’m not sure if it’s just me or what, but it separates sooo bad on my skin! I have tried using different primers under it, but I haven’t used it with foundation at all, and it still separates super bad! I’ve tried blending it with both a brush and a beauty blender, and although I usually set my make up with setting powder I’ve tried not setting to see if there’s a difference but there isn’t.. my skin isn’t super dry nor is it oily, so I don’t get it. Any tips or ideas of why it could be?
