Topical Bimatoprost is applied to the upper eyelids as a solution (liquid). It's commonly administered in the evening once a day. Every day, apply topical Bimatoprost at the same time. Follow the directions on your prescription label carefully, and if you have any questions, ask your doctor or pharmacist to clarify anything you don't understand. Follow the manufacturer's instructions for using topical Bimatoprost online. Do not take more or less of it, or take it more frequently than your doctor prescribes. Using topical Bimatoprost more frequently than once a day will not result in increased eyelash development.
