By definition, Careprost Eye Drop functions similarly to prostaglandin in that it increases the amount of fluid that exits the eyes, hence lowering intraocular pressure. It's well known that it can be applied to lashes. The recommended method of administering Careprost is ocular or through the eye. Before using this medication, wash your hands. To treat insufficient lash length, apply one drop of the solution using the applicator brush once a day.  If the bottle is broken or otherwise damaged, do not use this suspension. Avoid touching the dropper's tip with your hands or eyes as this could contaminate the medication.
