I have tried lots of different mascaras, trying to find one that darkens, lengthens, and adds fullness without clumping my poor lashes together. I've been a fan of ORIGINS Fringe Benefits mascara for years, but it just didn't add the volume I want sometimes. This one does!! I don't know if it's the formula or the brush, but to be honest, I don't care. Love this one...plus it doesn't irritate my eyes like some others I've spent waaaay too much money on. Two thumbs up!
