Hi, thanks for reaching out to me with your question. :) On Once Upon a Time during the episode "Quite a Common Fairy", David stated that pixie dust is "nuclear fairy dust". What he meant by it is it's a stronger version of the regular fairy dust that fairies use. Pixie Dust appears to be native to both the Enchanted Forest as well as Neverland. During the same episode, Tinker Bell stole pixie dust against the Blue Fairy's wishes in order to help Regina find another chance at true love. While in Neverland, pixie dust grows within flowers on a tree in Pixie Woods. Pixie dust grants a person the ability to fly. David and Hook once thought pixie dust could possibly cure Dreamshade poisoning, but since the theory was never actually tested, it's not known for sure if it works.

Regular fairy dust has many uses. Snow White once had fairy dust (black in color) that she said was from a bad fairy. That kind can transform a person into a harmless creature. The fairy dust that's made by dwarves from crushed diamonds is pink in color. Generally speaking, the pink kind is considered "good" magic. Belle used some of it in "The Outsider" to revert Phillip to human from his cursed form. And then there is the Blue Fairy/Mother Superior's fairy dust, which has appeared as blue in "The Cricket Game" when she used it on the Evil Queen/Regina to paralyze her.

If you would like to discuss this topic further with the wiki community, I would recommend this thread: http://onceuponatime.wikia.com/wiki/Thread:138208 since it talks about the differences between pixie dust and fairy dust.
