Just going slightly off topic. I found another clinic offering Active FX/Deep Fx treatments. They're based in the center of Manchester.
Seems like they're only applying the treatments on the face. I've enquired twice in the last couple of months regarding the use on stretch marks, and seems like they haven't had any trials with this.
They're called skinmedical .co.uk
Feel free to share some news if you have any luck with them.
