I have long eyelashes and a lot of them, and i found this formula to be way too thick and the brush is not good at separating each lash. It goes on clumpy and the brush bristles are too dense. If you are going to use this make sure to curl your eyelashes first and invest in a white or clear primer. It seems it would be good at adding volume, but i find it hardly looks like I'm wearing anything, except that my lashes are clumped together. I probably won't use this again.
