What is the recommended Pico Toning cycle for managing melasma and blemishes during the change of seasons?

With the sunlight getting stronger recently, dark spots on my face have started to become noticeable. I think it's time to even out my skin tone with a Pico Toning treatment. I've heard that Pico Toning is usually effective for improving complexion when received multiple times at intervals of one or two weeks. However, getting it too often can strain the skin, so checking the appropriate treatment schedule seems essential. I really want to get a thorough consultation and regain my clear skin. I'm curious how many sessions working professionals usually get. Please share your information!
