I've been using the Dark Spot Diminisher for almost 3 weeks and noticed significant reduction of my melasma. My melasma is pretty dark and covers a large part of my face. I used several products in the past, including prescription ones, which enlightened the affected areas for a moment but seemed to have activated the melanin increase in previously non-affected areas as soon as I forget to put enough sunscreen on.
I am happy with the Dark Spot Diminisher so far. My spots haven't disappeared yet, but I am hopeful they will soon. I combine it with Vital Reds; in my mind, the more antioxidants, the better for my skin.
Bottom Line: Yes, I would recommend this to a friend
