Will the blackheads from pico toning be erased?

I am hoping to see an improvement in my blackheads due to the picotoning effect, but I am curious to see how effective picotoning actually is.

I'm considering a treatment because I've been using whitening products and UV protection, but I've reached my limit. I've heard that pico toning breaks down melanin pigments to brighten skin tone. I'm curious about how many sessions I need to see the effects. I'd also like to know if the effects of pico toning vary depending on the type of freckles, blemishes, and pigmentation. Could you tell me the recommended treatment frequency to maximize the pico toning effects, whether pigmentation may temporarily darken after the treatment, and what the side effects and recovery period are? I'd also like to know how long the pico toning effects last with regular use.
