We had someone call us and ask us about an at home device. We told them these are very dangerous, just go online and see how many people have burned themselves. The people who work in a medical spa went to school for this and have extensive knowledge about lasers. You have to know about skin types, how to program the machines and more….we do free consultations here if you every want to chat about this. 519-542-0079 or karen.callies5@gmail.com
