Dermarolling at home for white stretch marks

Hi, I have many old white stretchmarks on my butt, hips and tighs. I´ve been reading a lot about using the dermaroller at home to improve them, so I thought Í´d try it. But then I read that dermarolling can hurt the skin around them, to the point that it creates even more. Is this true? Can it be more harmful? Thanks for the answer.
