Bimatoprost ophthalmic solution, commonly referred to as Lumigan drops, is a medication used to treat hypotrichosis, a disorder marked by sparse or insufficient eyelashes. Using the included applicator brush, Lumigan drops are applied directly to the base of the upper lashes. Over time, the drops aid in the development of longer, thicker, and darker eyelashes. It's crucial to use Lumigan drops in accordance with the directions on the package or as advised by your healthcare provider.
