I've tried Noni juice, tried it for about 3 months. I have EHK, so I'm not sure about other forms, but Noni juice did not help me at all. After 2 weeks it made my skin get really dry but never made it exfoliate in any way. It was "real" Tahitian Noni juice. I have also heard that Noni is under investigation by the FDA for making false claims about their product. I'm not saying it doesn't work, but it did nothing for me.
