Doubt It Would Help

 Call me a skeptic on this. If the other methods did not work, I doubt this one will. This technique uses small needles which penetrate the epidermis but do not go into the superficial dermis. If the Pixel, which is similar to the Fraxel did not work, and in addition the erbium laser did not work, I did whether the less aggressive treatment of the Dermaroller would work.

       You might try to find someone skilled with the pulsed CO2 laser which remains the gold standard of this kind of therapy. Another choice would be a physician, be it a board certified plastic surgeon or a dermatologist who is skilled in deep chemical peels or dermabrasion.

     Good luck. I know this can be frustrating.
