minimal effect for me
I've been using this every day for about 6 weeks, and for the most part I haven't noticed much difference at all.  It goes on like a clear liquid eyeliner, and it says to apply once a day, though I wound up bumping it up to twice a day just to see if that produced any effects.  I haven't experienced any noticeable lengthening of the eyelashes at all.  I've also been applying it on my eyebrows, also with minimal effect.  The only thing I can say is that it seems to encourage some *new* growth, though very inconsistently - only in spots where the lashes or brow hairs would likely have eventually come in on their own.  Overall, it didn't do enough for me to consider repurchasing.
