330 patients (210 females, 120 males) with 684 facial nevi – pigmented, elevated, with brown or skin color, papular or nodular shape and 2–10 mm in diameter.
CO2 laser treatments performed at 2-month intervals until complete clearance observed dermatoscopically:
- 3–10 ablative passes with square pattern, 30% overlap, energy 4–6 mJ and fluences of 20–35 J/cm2.
- Global Assessment Scale (GAS) scores used to assess the overall results.
554 nevi (81%) successfully treated in 1 session, 89 (13%) in 2 sessions, 34 (5%) in 3 sessions and 7 (1%) in >3 sessions. The majority of side effects were mild and transitory.
