It's only be a week and although I do not see any results yet, I am pleased to say I've had no pain or adverse side effects. During the procedure the first 5 minutes were slightly uncomfortable but the worst part was not knowing how much colder/uncomfortable it would get before going numb. Once I went numb and was no longer uncomfortable I realized that it really wasn't that bad in the first place. For me it was just the unknown that was scary. The 2 minute massage was painful. The warmth of the air and the technicians hands stung my cold skin and it felt like little needles. But it only lasts 2 minutes and I was never in so much pain that I couldn't speak to the tech while she massaged.
That night and the next day my chin just felt a little numb. One week later and the skin is very slightly tender but has never been painful. I also did not experience any bruising (which I was surprised about because I bruise very easily) and very little swelling.
I was told to expect to see initial results around the 3 week mark and the best results 10-12 weeks after the procedure. Once I have photos that show a change I will upload before and after photos.
I wrote this recap/review because I was VERY scared of pain during and after the procedure. I don't know why I did not experience pain but I'm very grateful that I did not and wanted to let others know that not everyone experiences it.
