Good, really good to some extent
Been using for 10 treatments now, the difference in my skin is good. More smooth and clear. However i'm not sure about its effectiveness on 'Hyper-pigmentation' some of the marks have slightly become less dark but I'm not sure how many treatments it will take to actually get rid of the major hyper pigmentation acne scars on my face, or if it even will for that matter of fact. Nonetheless good product, would recommend.
