I have two bottles of Latisse that have an expiration date of 5/2010. Are these still safe to use? Will the effect be lessened? What is the after expiration shelf life?
Many medications are actually still quite effective long after their expiration date. The dates are usually there because of FDA requirements. If you're using a product after its expiration date and it seems to have less effect then it's time to replace it. Other risks, such as infection, would be very unlikely.
