What is the risk of CO2?

Hi! I’m planning to get CO2 treatment done at the end of March. I’ve been wanting the treatment for a few years now and I’ve had multiple providers (dermatologist and PAs) tell me that this will be the best treatment for my acne scars. I’ve had 6 SkinPen treatments done and they helped reduce some texture and redness but honestly didn’t help much… I’m tired of wasting my money on small treatments and I just want to go for the big one at this point.

I found a PA who I really trust in my area that offers CO2 treatment. She seems to be highly qualified and knowledgeable. She has plenty of good reviews, he business has been open for a long time, and she is able to show me her personal results. She actually trains other providers around the states on how to properly do CO2 treatments.

I guess my question is… what is the risk of this treatment? Are there risks? I want this done so bad but I’m also scared. I have this weird fear that maybe this will make things worse or something will go wrong. I’m sure it’s just anxiety but any thoughts?
