Since there were issues with the mail delivery in Canada, I didn't receive my package of the dark spot remover until two weeks ago, so I have only begun to use it daily. I feel it is doing its job as the spots are not getting any darker and some are diminishing in color. An interesting sidebar is I also notice the spots on the back of my hand where I deposit the serum before l place it on my face, has also shown the spots fading. I am anxious to see what the next month of application brings to my spots!
Bottom Line: Yes, I would recommend this to a friend
