Great stuff and I didn't get it for free!
After seeing all the reviews by people who got the product for free, I was a little hesitant to buy this.  I wondered if it would really be that good, and while it wasn't terribly expensive, it wasn't cheap, either.  But not to fear ---  I paid full price, and yes, it works.  It took a number of weeks for me to see results, probably because I wasn't  very consistent in applying it.  I have very sensitive skin, and I had no stinging or burning.  There might be an occasional tingling sensation, but usually nothing at all.  My lashes were always long and thick and full, but in the past several years (since hitting my 50's) they have been thinning out.  This product has restored them  to the original thickness I had in my younger years.  I try to use it at least once a day, but sometimes miss a day or two.
