Latisse has never been shown to change the color of the iris. The product began as an eye drop for glaucoma, and it was only in this use that eye color change occurred. Since it was repackaged into the topical eyelash form of Latisse, no patients have reported this event. Since Allergan has a patent on the active ingredient, you are unlikely to find an alternative with bimatoprost as the active ingredient. And I have seen no data that shows something else works.The starting color of the eye is also an issue. Hazel and light brown eyes were the ones that darkened with the glaucoma prep. The incidence of that was very rare. Blue eyes do not darken.
Latisse MAY turn eye color to brown ONLY if the product is applied to the surface of the eye for a prolonged period of time. It will not do so if applied only to the junction of the upper lid and its lashes as instructed by Allergan - the Latisse maker.While a feverish race is on to find the next Latisse and despite many claims of growing lashes THERE IS AS YET NOTHING OUT THERE that does it. So - your choices - heavy mascara or fake lashes and nothing while waiting for the next Latisse OR using Latisse properly.To learn EVERYTHING you need to know about Latisse, follow the comprehensive link below - Dr. Aldea
