I'm in my early 20s and I'm worried about my double chin. I've had Inmode a few times and I've seen some results, but I get bruises easily and the bruises last for 10 days..? They say that Tuneliner doesn't cause bruises so I'm curious. Is it as effective as Inmode..? And how long does it last? Inmode lasts for 1 to 2 months so I'm worried... Tuneliner is expensive so I'm worried that it might last as long as Inmode. Has anyone tried it before? What do you think?
