I'm curious about the picotoning cycle.

I'm considering pico toning to improve freckles and blemishes, but I'm curious about the recommended pico toning cycle. I'd also like to know if the pico toning cycle varies depending on skin type and pigmentation depth. I'm also concerned about the risk of skin irritation or side effects if the pico toning cycle is too short. Could you also share some management tips to maximize the results?
