My iris color changed?

Latisse can cause pigment changes to your iris. Latisse can also cause pigment changes to the skin where it is applied. A photo would help to assess the color changes. There is contact information in the Latisse box with the directions. I would direct any concerns to the manufacturer. 

There is no "over the counter" equivalent to Latisse because it is a prescription product. It contains an ingredient called bimatoprost, which is also used in a different formulation called Lumigan for glaucoma. A small percentage of patients with green/hazel eyes experience color change to brown with Lumigan, which is applied as drops into the eye. Latisse is not applied into the eye so there are no confirmed reports of iris color change. I have no idea what is in rapidlash but it is not the same. I would recommend consulting an ophthalmologist.

Latisse is the only FDA approved treatment documented to enhance eyelash length, thickness, and color.  When used as a drop in the eye for the treatment of glaucoma, a small percentage of patients (1-3%) noted change in the color of the iris from green to brown.  This has not been reported when Latisse has been used appropriately on the outside of the eyelids.  I am not aware of any studies demonstrating ocular effects of Rapidlash.  I would contact the manufacturer for more information.
