My lashes are short and fine, making it VERY difficult to find a mascara that 'works' for me. I have tried SO many brands that advertise volume and length but just do not work for someone like me who was not blessed with nice eyelashes. I have worn it alone and under mascara - either way, I love it! The wand is perfect (especially the tip) for getting at the shorter, finer lashes on the inner and outer part of my lids. It doesn't clump. It doesn't glob up after a second application. It doesn't really do anything to lengthen but it separates and absolutely does not clump so....no spider lashes AND the fact that it separates so well, makes up for the lengthening. Absolutely worth EVERY penny! BUY IT, BUY IT, BUY IT!
