No I haven't, but I have had next to no eye lashes so fake ones that *could* trash your lashes aren't something I am comfortable with. Back in 2010 I bought waterproof mascara and then I started losing all my lashes. Once I realized it was the mascara and I switched to non-waterproof I was ok, but it took forever for them to grow back. I had to use a thick black eyeliner to give the impression they were there.
I think it's a prescription serum that you put on your eyelashes to make them grow.
I'm currently using this Rimmel Lash Accelerator Serum that you can get at drug stores that some people swear produces the same results, but I don't think I remember to use it consistently enough to vouch for the results yet, but I'll try to be better about using it every day and report back!
Ohhh now that you say that a friend of mine swears by this medicine you put on your lashes. She asked me to get her some from the Pharmacy in the Cancun airport. I should ask her what it is called, not that that helps us in US/Canada but maybe you US ladies have access to it.
