Bimatoprost belongs to a class of medications known as prostaglandins. It works by opening the channels that drain fluid from the eye, helping the excess eye fluid to drain from the eye more easily. By reducing eye pressure, the medication can help prevent damage to the optic nerve (and the vision loss that accompanies such damage) caused by high eye pressure.
It is thought that bimatoprost works to make eyelashes darker, thicker, and longer by increasing the number of eyelash hairs that are in the active growth phase and also by increasing the length of time the hairs stay in the active growth phase.
