Careprost Amazon, which contains the active ingredient bimatoprost, is primarily used for the treatment of hypotrichosis, a condition characterized by inadequate or insufficient eyelashes. It is applied to the base of the upper eyelashes to promote their growth, length, and thickness.  In addition to its use for hypotrichosis, bimatoprost is also used in the treatment of glaucoma, a condition that causes increased pressure in the eye. It helps to lower intraocular pressure by increasing the outflow of fluid from the eye.
