How Does Latisse Affect Eye Color?

This is a confusing issue. Lumigan has been found to possibly darken the iris color. This is most risky for blue eyes which can become hazel. In their studies, Latisse (which is the same medication but is not applied to the eyeball iteself like Lumigan) was not found to cause this problem. Allergan felt that it was safer to warn patients about this possibility because if it does happen, its permanent. Hope that helps!

Latisse has never been shown to change the color of the iris. The drug Lumigan, which is a glaucoma medication in the same family as Latisse, has been shown to deepen the brown pigmentation in blue eyes, so this prompted a warning on Latisse. This side effect has never been seen, to my knowledge, in patients using Latisse. Remember, Latisse is used on the eyelid, so very very little of it ever enters the eye.

The iris of the eye has pigment in it, much like hair. This pigment, or melanin in some cases of patients using the glaucoma drop Lumigan, had their eyes become darker by the activation of the cells that produce pigment. It was most noticable in lighter colored eyes that became darker, and the change was permanent. In the case of Latisse, it is exactly the same medication (Brimatoprost 0.03%) but if applied properly, does not go into the eye, or in very tiny amounts and there has been no... more

Latisse is a prescription-only solution that has been scientifically proven to stimulate the growth of eyelashes. There is no evidence to suggest that Latisse will change your eye color. The eye is exposed to a very small amount of Latisse even when it is properly applied as directed to the upper eyelid margin using the supplied applicator. This has been demonstrated by applying a colored dye to the eyelid margin and watching its migration. Over two million prescriptions for Latisse have... more
