I have a question regarding the recommended number of Pico Toning sessions!

I was looking into toning treatments because my skin tone is dull, and I heard that Pico Toning is very effective. However, before going for a consultation, I am posting this question to know the approximate recommended number of sessions. I have heard that it is usually difficult to see results with just one session and that multiple treatments are necessary; what is the average recommended number of Pico Toning sessions?

Even if my skin condition isn't severe, would it be better to generously schedule at least 10 Pico Toning sessions? Or am I wondering if I can feel a noticeable difference with about 5 sessions?

I’ve heard that it’s more important to stick to the appropriate intervals and recommended number of Pico Toning sessions rather than blindly receiving many treatments. It would be a great help if those who have actually seen results could share how many sessions they received in total. Please let me know if you have your own personal criteria for the recommended number of sessions!
