I only did the philtrum and front chin, and the cost per session was about 40,000 won, which was cheap. To be honest, I was annoyed because some areas of pigmentation appeared, but I was satisfied with the follow-up response. I heard you use the Apogee Plus, but I haven't used the Zen Mac Pro, so it's hard to compare, but it was moderately painful and it was over quickly, so it was bearable.
