i recently discovered this brand through birchbox. as a libra, i really like options, and i also have a friend named marcelle, so i couldn't resist trying this mascara. :)
this mascara is not for makeup novices. this truly is a serious mascara with two different brushes in one package. when you first pull the wand out, the brush is extended and you apply one coat with the brush in that position for long, defined lashes. then, if you twist the base of the wand, the brush compresses for volume. you can either re-dip the wand or use the leftover mascara on the second step. either way, this combo creates perfectly defined lashes with no clumps and no wilting.
be warned though, that this is not really for a quick swipe of mascara when you're running out the door (if you're going to do that, i suggest skipping the first step and using the compressed brush). i also do not recommend two coats using only the extended brush because i wound up with lashes that looked incredibly fake. you need to pay attention with this one but it's well worth it.
