Is Pico Toning suitable for managing acne scars and dull skin tone?

For the past few months, I have been experiencing recurring acne around my chin and cheeks, resulting in increasingly more brown marks in addition to the red ones. My entire skin looks dull and patchy, so even when I apply makeup, my skin doesn't look clean; that is why I am looking into Pico Toning. I am wondering if Pico Toning is a recommended option for those like me who want to manage both the brown pigmentation left behind after acne and an uneven skin tone. I would also like to know if the expected effects or treatment intensity vary depending on the type and depth of the pigmentation. Is it difficult to notice changes after just one session? What are the typical recommended number of sessions and treatment cycle, and how long does it take for the effects to appear? Since my skin is thin and tends to dry out easily, I am curious about pain, post-treatment symptoms such as redness, stinging, and peeling, and the recovery period. I would also like to know the price per session, the estimated total cost for multiple treatments, and the duration of the effects. I would like to consult with you regarding whether the treatment can be continued even if new acne appears during the session, as well as precautions regarding cleansing, makeup, and sun protection. If it is suitable for my skin, I would like to start the treatment. I am also curious to read reviews from people who have received the treatment for similar skin concerns.
