Is CO2 laser or Erbium laser better for flat mole removal on my East Asian skin? (Photos)

My moles have been checked by derm to be non-cancerous. One doctor is offering CO2 laser and another is offering Erbium laser for my flat moles. I have a fair few of them on my face. I have read that Erbium laser gives better result than Co2 laser because it transmits less heat and does less damage? My main concern is recovering from the indentation that the laser causes and discolouration. I don't want to dent and I don't discolouration. Thank you. Stay safe!
