I didn't see a crazy miraculous change over the 2 weeks that I have been using it, but I did notice that my lashes grew. While there wasn't a "wow!" change, I had a small section on my lash line that was totally lash-less, and I completely saw new lashes starting to grow there. Last thing: just know that you have to apply it daily. Lashes fall out, you can't apply it once and expect the results to stick.
