This is one of my favourite eyelash primers I've tried (I've tried the one from Lancome, Dior, and MAC). I love that the wand is smaller than your typical mascara and eyelash primer brush. This means you can really get in there and coat all of your lashes. The consistency is also like a gel and even though the product is actually purple (the purple does not show up on your lashes) it is not super wet such that it will make your lashes droop. You can put your mascara on right after applying this or after a few minutes; I found that I get the best results when I apply mascara after ~10 seconds after primer application. The Anna Sui primer makes my lashes look thicker and longer.
