How many sessions should I determine the recommended number of Pico Toning treatments?

I'm looking into Pico Toning for my freckles and blemishes, but I'm confused because everyone says you need different amounts of sessions to see results. Some places say you see results after 3 sessions, while others say you need 6. I'm not sure if it depends on your skin condition or the type of pigmentation.

I am also curious about the interval for Pico Toning treatments. I want to know if I receive them every week or every two weeks, and how to perform maintenance after completing the full session. I am also wondering if the effects of Pico Toning last after the treatment is finished, or if they will return if I stop receiving treatments.

For those of you who have received Pico Toning, it would be really helpful if you could share your experiences on how many sessions it took to notice changes and how you are maintaining your results!
