Can Revitalash cause permanent iris color change?

Thank you for your question! The only reason why eyelash serums like Latisse and Revitalash have that risk listed is because one of the ingredients is the same as glaucoma eye drops which have been known to cause color change in light colored eyes.  The ingredient is so low on the list of the eyelash serums, that it has never happened for patients who use Revitalash or Latisse. The companies have to list that as a risk due to that ingredient.  Rest assured that your eye color will not be affected!
