How many Pico Toning sessions are usually recommended to see results?

I consulted a dermatologist about my freckles and blemishes and was recommended Pico Toning.

However, I heard that this isn't a one-time thing but requires consistent treatment. So, I would like to ask those who have actually experienced it what the exact recommended number of Pico Toning sessions is.

I heard that the standard recommended number of Pico Toning sessions is usually around 10, but I was told that the recommended number can vary depending on an individual's skin condition or pigmentation depth.

I am worried that receiving it too often might strain my skin, and I am wondering what the minimum recommended number of Pico Toning sessions is to expect noticeably clearer skin.

I would be really grateful if you could give me some tips on a realistic recommended number of Pico Toning sessions, along with regular intervals!
