I can't live without..
My Lancôme primer. My friend first told me about this primer and I was intrigued. It comes on white and you put it on before your mascara. It gives your mascara whether drugstore brand or luxury brand major staying power.
I have long thick lashes that I curl. I like putting the primer on and adding either Rimmel Scamdalous mascara or Makeup for ever Smoky Extravagent. I love how my curled lashes stay all day and look much thicker.
It's a must have product if you ask me.
