Will Pico Toning help with light acne marks as well?

I don't have severe acne scars, but I have light brown spots remaining on the sides of my nose and cheeks where I used to have small blemishes, so I am looking into Pico Toning.

It isn't uneven indentations; the skin surface is flat, but there are small areas visible that are just different in color.

I thought it would naturally disappear over time, but some parts lingered longer than I expected.

Can I expect Pico Toning to be effective on these types of pigmented marks as well? I am also curious if Pico Toning manages general blemishes and pigmentation remaining after breakouts in the same way.

I'm worried that the marks will recur if new breakouts keep appearing even after getting Pico Toning, so I'd like to know if it's better to start after my acne has stabilized to some extent.
