How should I set the picotoning cycle?

I'm currently looking into pico toning treatments because I'm concerned about blemishes and freckles on my face. However, I'm confused because the pico toning cycle varies from person to person. I'm curious about how often pico toning is recommended for best results, and if it's too short a cycle can cause skin irritation. I've read online that 2-4 week intervals are generally recommended, but I'd also like to know which pico toning cycle you found most satisfying. It would also be helpful if you could tell me how pico toning cycles vary depending on skin type and condition. I haven't decided on the procedure yet, so I'd like to hear various opinions.
