Bimatoprost is a medication primarily used to treat increased intraocular pressure in individuals with glaucoma or ocular hypertension. It works by enhancing the drainage of fluid from the eye, thereby reducing pressure and helping to prevent damage to the optic nerve. Additionally, Bimatoprost is also used in cosmetic applications to promote eyelash growth. It is often found in products designed to make eyelashes longer, thicker, and darker. The medication is typically applied as a topical solution to the base of the eyelashes.
