Is dermarolling going to ruin my skin? I've read a couple of things about it making people's skin deteriorate. (Photo)

considering dermaroller to improve the texture and thought it was a safe alternative to laser but I've read a couple of things about it makin people's skin deteriorate and making them look older. Can this happen!? I'd really like some impartial advice off people I don't know as I have my consultation next week and when I booked my FREE consultation they were trying to make me put down a 20 pound deposit for the procedure which I hadn't even agreed to get. I'm 25 mild sun damage.
