I got a sample of this and was instantly intrigued by the silky texture. It felt great on my skin, and of course the sample was not enough to determine how well it was working on dark spots, but I loved the way it felt. And having purchased the full size version and using it continuously, I think it does help. And it feels great! One word of caution, because of the high vitamin c content, it will sting if you apply it on irritated skin. So stay away from sensitive areas.
