It only took a week for me to notice a difference in the length of my eyelashes using this Lash Enhancing Serum. I couldn't believe how fast it worked! I only use it at bedtime on my top eyelids. I've gone through 3 bottles and am now on my 4th bottle as I just reordered and will continue to do so when I run out. I've found for myself that even if I forget to use the Serum for a few days, my lashes stay long. I estimate that they are approximately 1/8" longer than when I began using the Serum. With some mascara, I can say that my lashes are lovelier looking than they've ever been.
Bottom Line: Yes, I would recommend this to a friend
