like most things [SEP] like most things there are pros and cons my eyelashes had gotten very sparse and short over the years in some places there were none at all i used this product very faithfully twice per day first of all yes it stings your eyes if you get it in them i did think it was very easy to apply i have used it for about six weeks on both my top and lower lashes i do appear to have some lash growth and when i apply mascara my eyelashes do look like i at least have some i am going to continue to use up the tube and then try something else maybe i was hoping for something too dramatic and should be glad it worked at all i have read the other reviews and a lot of people are saying they have seen a very dramatic response just wish i were one of them
