Latisse Expires in One Month - OK to Use Beyond That?

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. So it should be fine to continue using the Latisse for quite a few months after the expiration date until it is gone.
