stings your eyes [SEP] i ordered this veta lash and eyebrow serum in lash brow pen for review my teenage daughter was willing to try it out for me and these are her thoughts the pen application is not difficult however if you accidentally get it in your eyes it stings really badly i had used it a couple of times before that happened but now i do not want to use it again unfortunately she did not use it long enough to see if there was any lash growth if my wife is brave enough to try it i will update my review
