I too have tried all of the Fraxels. None of offered much improvement.
Thus far, three months have passed since I have done the latest Fraxel -- Fraxel Re:Pair. I have seen little to no improvement in acne scars, wrinkles and tightening. I have been told that it can take three to six months to see improvement, but I really doubt it at this time.
I have been taken, but others should pay attention to this review and not waste their money too. I'm still hoping for a Genie to hop out of the bottle, but there was no Genie here.
