) Immediately after treatment
with two passes of the UP CO
2
laser on the right side of the face at a setting of 300 mJ, computer pattern generator with a density of 5 followed by two passes with
the Er:YAG at 5 J/cm

. The left side was treated with the Sciton laser using a 50 μm of ablation and 100% coagulation for two passes followed by two passes with 0%
coagulation and 5 J/cm

. (
C
) 2 days after treatment, the CO
2
laser-treated side is more swollen and erythematous. (
D
) 1 week after treatment, the CO
2
laser-treated
side is more swollen and erythematous. (
E
) 3 weeks after treatment, the CO
2
laser side is more erythematous. (
F
) 30 weeks after treatment, there is no appreciable
difference between both sides of the face.
