How often is Pico Toning usually administered?

I am considering Pico Toning because of light blemishes around my cheeks and an overall dull skin tone, and I am curious about the treatment cycle.

I’ve heard that Pico Toning is often received multiple times at regular intervals rather than being stopped after just one session. In reality, how often are sessions typically performed?

My skin tends to be dry and turns red easily when I'm not feeling well, so I'm worried that repeating this at very short intervals might put a strain on my skin.

I am also wondering if the Pico Toning cycle can be determined individually based on skin condition or the degree of pigmentation.

Is it possible to receive Pico Toning once to check the skin's reaction before deciding on the next treatment date? I would also like to know if, after some improvement, the treatment cycle is extended for maintenance only, or if intensive care is resumed at regular intervals.
