honestly couldnt get it into my routine long enough to see if it truely works [SEP] so far i could not get this product in my routine for long enough to see how well it works at all i do not want to give it a bad review because of my lack of ambition with it but i do not want to lie and say that its an amazing product either this biotin infused zenlash eyelash growth serum is definitely easy to use it comes in a little wrapped bottle similar to a mascara bottle except the brush looks more like a detail nail polish brush the idea is simple you brush it on your lash line everyday and wait and watch it was a bit hard for me to get my lid closed all the way and brush this one but i am not one who uses make up much either if you do use make up it will probably come a lot faster for ya i did accidentally get a bit in my eye before and i was happy to see though it does not feel good it did not irritate me much either i really wish i could say that i saw a huge transformation but after only managing to use it for one straight week i did not see much difference thanx
