I've been using this on my cesarean scar for 3 weeks and the difference is amazing. Scar is 2 years old, the redness has completely disappeared and the actual tissue is slow becoming more flat. I find the process relaxing. I run the PEMF along the scar line, usually taking 3 sometimes 4 sessions to complete the scar. I try daily, ideally am and pm, but sometimes it's every other day. Highly recommend trying it out on a scar!
