Do I use it on my lower lashes too?

By applying Latisse only to your upper lash line, you are. Because Latisse is applied before you go to bed each night, when you close your eyes to sleep, your eyelids touch each other and some of the solution may be transferred over. Thus far the clinical trial was only used on the upper lash line. Overuse of Latisse can lead to the aforementioned side effects. It is always safest and most effective to follow directions.
