I purched the DERMAWAND from an infomercial on TV. This product is a Spa Treatment at home. DO NOT BUY THIS PRODUCT. It burned my face - still burned now after 6 weeks! I only used it 3 times at the lowest setting - it stings badly and after 3 weeks have not received my refund. BTW - I am never again buying anything from infomercials because every time I have called they put huge pressure for you to buy more with inticing offers.
