They say that in order to have a completely finished look, you need to "do" your brows. Let me just say, that's 100% true. Love this on my brows! I do a couple of quick swipes on each brow and it helps fill them in where it's needed. Just enough to make the eyebrows "pop" a little more, but doesn't look fake. It just looks like I have nice, full eyebrows. I will always fill in my brows now since Boots has made it so easy!
