such a great product. really make my lashes look healthier  

This lash serum makes my lashes look healthier, and makes them fall off less when you use a bad mascara, it call also be used under mascaras that are try, like the Better than sex mascara  by Too faced, as it made my lashes fall off because of its very dry formula, but this helps a lot, as it makes the consistency more gel like, and no fall outs of dried mascara.  

I´m not sure yet about this I don´t feel like theres a big difference! 

Doesn't do anything...and changed into a cloudy mess after a month. I am now using plain old castor oil and it is working wonders.
