How long does it take to see results from Viora Reaction skin tightening?

I'm having Viora Reaction skin tightening done. I've had 3 treatments on my face & neck and don't see any improvement yet. I purchased 8 sessions. When will I start to see an improvement? (the before & afters are impressive -but I don't see any improvement in my skin). and my neck is usually very red after the procedure.
