What are the side effects of ematix/sublative treatment? (photo)

I had sublative treatment done yesterday on it's highest setting for scarring. I am very worried after reading really bad reviews about permanent damage/pockmarks/blotchy skin, and skin being "ruined" after treatment. I am a 30yr old olive skinned asian. My partner is 47yrs old, caucasian,very fair & he wants it for his wrinkles. His skin is sensitive. Can you please explain why there is such a huge contrast between reviews? from extremely bad to good? Can it damage your skin?
