I have sensitive skin and am concerned about a dull tone. Won't Pico Toning be irritating?

I am concerned because I frequently hear that my complexion looks poor due to my overall dull and uneven skin tone. While searching for a procedure to brighten my skin, I received a recommendation for Pico Toning, which is said to have few side effects and be highly effective for improving complexion. However, since my skin is quite thin and sensitive, I am worried that the laser treatment might cause further redness or severe irritation. I would like to know if Pico Toning is safe for someone with sensitive skin like mine, and how long the redness typically lasts after the procedure. Additionally, if you could provide detailed information on how many repeated Pico Toning sessions are usually required to achieve satisfactory whitening results, it would be a great help in making my decision regarding the treatment.
