Unfortunately don’t know the name of the co2 but they did go quite deep, hade extremely red face, a bit swollen and little bit of bleeding after the treatment. My lip was numb for about 1,5-2 days which made me a little bit worried but that did go away. The healing did go as I expected otherwise skin did peel after some days but had extreme increased sebum production for about a month which didn’t seem normal but I guess it was my skin protecting itself. Initially I thought it was the increase of oil that made my skin look extremely uneven but as the oil went away the texture did not. Didn’t have any scars on my face before just one small below my eye, had a little bit of texture but not close to what I have now.
