Careprost is a brand name for a medication called bimatoprost ophthalmic solution. It is primarily used to treat hypotrichosis, a condition characterized by inadequate or insufficient eyelashes. Careprost drops contain the active ingredient bimatoprost, which helps promote the growth of longer, thicker, and darker eyelashes. Careprost drops are applied topically to the base of the upper eyelashes using an applicator brush that comes with the product. It is important to follow the instructions provided by your healthcare professional or as indicated on the product packaging.
