Pico Toning Effect: Is there a time when the skin tone is uneven?

Lately, when I look at the skin on my cheeks, it doesn't seem to be a uniform color with subtle differences in brightness in certain areas, so I am inquiring about Pico Toning.

Rather than being bothered by a single specific blemish, my concern is that my overall skin tone is uneven, making my face look a bit tired and dull. While makeup covers it initially, the difference in skin tone seems to reappear over time, so I would like to receive a treatment that addresses the root cause. Would Pico Toning be effective in this case?

I am curious if Pico Toning is used not only for small blemishes but also to naturally even out the overall skin tone.

I don't expect my skin to suddenly become whiter just by getting Pico Toning; I'd like the tone to become a little more even than it is now. I'm also curious how many sessions you would expect with this goal.
