What is the treatment cycle for Pico Toning? Is the effect guaranteed?

I've been doing some running lately.

Because I do outdoor activities often

At some point, it feels like dull blemishes on my face became really noticeable.

I can see that the pigmentation has increased significantly.

It seems like the Pico Toning treatment has been well-received for a while now, and

An acquaintance of mine has tried it once, so I have a good impression of it.

Is the Pico Toning laser effective for improving pigmentation?

I'm also curious about how much skin irritation it might cause.

Since I have extremely sensitive skin, I wanted to inquire about how sensitive a person's skin can handle Pico Toning treatment.

I'm also curious about the approximate treatment cycle for Pico Toning.

For those who have actually received it, are you satisfied?! I'm so curious.
