Seeing white spots and pigmentation on skin - are these permanent? (Photo)

hi doctors, I'm seeing white dots on my arms and legs, you can only really notice them from up close, but theres a lot of them, and Im sure its from the laser hair removal that I have been getting done. THis is really bothering me as I have no idea, if this is permanent and what exactly causes it? And how can I prevent it, because I really want to keep getting laser hair removal.
