I had a full size (and used it up…twice) before Influenster sent me a free travel size which was a god send! This primer makes any mascara better, no matter what the price tag is. I always comb my lashes, then apply this primer first on top of the lashes and then from the bottom, then use mascara before it dries for the best effects. It helps with clumping and flaking, and makes cheaper mascaras look and wear better! Definitely a staple for my big nights out.
