is a medication primarily used for the treatment of hypotrichosis, a condition where there is inadequate or sparse growth of eyelashes. It contains two active ingredients: bimatoprost and timolol. Bimatoprost is a prostaglandin analog that helps promote the growth of eyelashes by prolonging the anagen (growth) phase of the eyelash hair cycle. Timolol is a beta-blocker that helps reduce intraocular pressure by decreasing the production of aqueous humor in the eye.
