It does work!
So I've been using this for about 3 weeks.  My lashes have definitely gotten longer, and I have gotten random complements on how long they are.  Week one...the serum does have a warm tingling sensation the first few days of use, but no redness or irritation for me.  I don't notice it anymore.  It seemed like I was losing more lashes, but nothing noticeable.  Week two...noticed my lashes are longer and there is new growth.  There are lashes where there weren't before like the inside and outside corners.  Still getting longer.  Don't notice that they are any thicker or darker.  Week 3..longer still, more of them.  Looks great with mascara on.  They seem to change every day.  Not losing as many now.  I can now see the changes even without mascara.  Easy to use, and it seems like I still have a ton left.  Great price for this product to when I have seen them for hundreds of dollars.  I will definitely keep buying!
