I've used this regularly for five months at the time of this review.  There is no noticeable difference in the color and thickness of my lashes.  I have not noticed more lashes either.  The lashes I do have appear to be longer and don't shed as quickly, so there's that.  I had higher expectations. I do have some lightening of the skin at the base of my lashes where the product is applied.
