A CO2 laser, which has powerful transpiration and coagulation abilities, is an effective tool for removing extensive tattoos; however, post-operative hypertrophic scarring is inevitable and is more severe than that caused by ordinary treatments.
The reasons why severe hypertrophic scarring occurs after treatment using a CO2 laser are as follows:
1) The tattoos are at regions where keloid and hypertrophic scaring tends to occur.
2) Patients want to manage the wounds themselves after treatment; however, this usually causes wound infection.
3) The powerful transpiration and coagulation abilities of a CO2 laser damage the tissues around tattoos and delay wound healing.
Nevertheless, patients can be satisfied with this treatment because it completely removes tattoos.
