I'm curious about skin laser treatments.

The pimple on my face lasted a long time and turned into a mole.

I previously received CO2 laser treatment twice, and it became faint, but now it's back to how it was.

I keep noticing my face every time I look, and it's bothering me ㅠㅠ

I'm wondering if I need to increase the number of times I receive it.

I haven't tried any other lasers besides CO2 laser, so I want to try a good laser.
