Bimatoprost is primarily used in ophthalmology to treat conditions related to eye pressure and eyelash growth. It is commonly prescribed to manage glaucoma and ocular hypertension by reducing intraocular pressure, which helps prevent optic nerve damage and potential vision loss. The medication works by increasing the outflow of aqueous humor from the eye, thereby lowering pressure.

Additionally, bimatoprost is applied topically to enhance eyelash growth in individuals with inadequate or thin lashes. It promotes longer, thicker, and darker lashes by extending the growth phase of the hair follicles. This cosmetic application has made it a popular ingredient in certain eyelash serums.

When using bimatoprost, patients should follow medical guidance to minimize potential side effects, such as eye irritation, redness, or darkening of the eyelid skin.
