Watch the video above about this spectacular mascara. I have tried many mascaras and most even though they state they are water proof, run the moment they come in contact with moisture. I have been wearing this mascara every day for months now. One of those days I spent almost the entire day crying, as a teacher saying good bye to a school I had been teaching at for 3 years. I needed a mascara that would not run, after the entire day of farewell parties and saying good bye to some amazing people. My mascara had not run even a little bit. I was able to have & keep full beautiful lashes all day long even through crying!
