I have a one cm pigmentation spot on my cheek where some freckles have joined together!, and bought this product to see if it would help get rid of it. But as I've only been using it for just over a week, I haven't yet seen any difference. I have noticed that my complexion looks more even and smooth though, so I'm hoping that after continuous use the 'spot' on my cheek will; if not disappear completely, at least fade so that it doesn't show through my foundation.
I find I only need one drop to cover my cheeks, and use it am and pm followed by the Vitamin C cream.
The serum has brightened my skin and made it soft and clearer.
I have nearly finished my first bottle and have purchased a second one.
I think it may take a while for the product to work on my large area of pigmentation but I can see a very small improvement after one bottle.
