This is the best mascara that I have found for bottom lashes--it stays in place for well over 14 hours without smudging or flaking but washes off easily.
I discovered it a few years ago and have been using it every since. Great for intended purpose of lower lashes (mine are long but sadly they are greying). Also works well for corner lashes (both corners) and for tips. I've given it as a gift and recommended it to others.
I love that the bottom lash stick makes it easy to apply the mascara without smearing which happens when using the full size stick. A tiny short mascara stick for lower lashes. What could be better!
