I haven't tried it, but know someone who has. She is extremely hapy. You don't actually bleed, just get red for few minutes. You can use ice before and after rolling. She swears her skin, drk spots, so much better. Her crows feet are almost gone after four months, she stoped having Botox there. I must say, she does look good. It costs $100-120, if you order, get the 2mms needles, most effective.
