How often should I schedule Pico Toning treatments?

Lately, blemishes and dark spots have been popping up one by one on my face, and it makes me so upset every time I look in the mirror. I heard that consistent Pico Toning treatments can clear up your complexion, so I'm planning to start. However, how often should I schedule Pico Toning for the best results? Some people say once a week, while others say every two weeks... I'm wondering if once every two weeks is generally appropriate and doesn't strain the skin. Since recommendations vary slightly from clinic to clinic, I'd like to know what the actual routines are like for those who receive consistent Pico Toning treatments. I'm also worried that going too often might make my skin sensitive. Please, those of you who know about this, I really need to answer! Thank you.
