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.  

Good product. My eyelash growth longer with it. Price is cheap as well

Also felt like it made my lashes fall out :^(
