Let me just say that I am super low maintenance when it comes to my brows. Until the past year, I never did anything more than just brushing them into shape. Since I feel like my brows are full enough to not be filled in, I've been dabbling with clear mascara or clear brow gel.
This elf Clear Lash and Brow mascara was the first official brow product I ever used. I had no expectations except for it to keep my brows in place. It did the job and even darkened them slightly so my brows weren't dull. I never thought I could say that, as my brows are quite a lot to keep up with, but putting on just a clear mascara really made a difference.
The mascara is just $2! And it lasts a while, My sisters gave it to me half used already, so I'd imagine it can last definitely over a year. My only complaint is that sometimes it can get a bit too crispy if you don't brush out the gel with a spoolie or some brow brush. And I also don't see the need for the two parts if they both do the exact same thing...
Otherwise, it's a great deal for the price and I'll most definitely be going back to this from time to time!
