How many people use Latisse? Can it permanently darken the iris?

Latisse is a product that is quite commonly used. There is the rare possibility in which it can darken the skin on your eyelids, or if you have blue or green eyes it can cause brown flecks if the product is directly deposited into the eye, which it should NOT be. It is very important that when using Latisse you follow application instructions carefully. Latisse medication is intended for upper eyelash use only, but it is perfectly normal that once applied and you close your eyes some medication will naturally transfer to your lower lashes as well. You can discontinue Latisse medication at any time and your lashes will revert back to their original state and growth pattern. Best to consult with an expert provider/nurse aesthetician in order to assess whether this might be the right treatment for you.

Latisse® use may cause darkening of the eyelid skin which may be reversible. Latisse® use may also cause increased brown pigmentation of the colored part of the eye which is likely to be permanent. While very infrequent, increased iris pigmentation has occurred when Latisse® was administered. In patients who use bimatoprost (the active ingredient in Latisse) for glaucoma, the incidence of brown pigmentation of the iris occured at a rate of 1-2% in clinical trials.

Latisse is different packaging of a glaucoma drop. Patients who used that drop were noticed to have permeant darkening of the iris and lash growth. That is why it should only be applied as directed to the upper lid lashes with the applicator  and kept out if the eye.
