How is the Pico Toning cycle usually determined?

I would like to inquire about the Pico Toning cycle.

I have an important appointment around the end of next month, so I’d like my skin tone to look at least a little bit cleaner before then, but I’m not sure if it’s okay to start now haha.

My entire face isn't extremely dark, but I have fine pigmentation on my cheeks and cheekbones, so my skin feels a bit messy in photos. I've read many posts saying that Pico Toning isn't a treatment that brightens your skin drastically after just one session, and that you need to receive it consistently over several treatments. I'm wondering how often Pico Toning is typically done, and when would be the best time to start if I have an important event coming up.

My skin doesn't tend to turn red easily, but I'm a little worried that it might become dry or temporarily sensitive after the laser treatment.

I would also like to know when I can wear makeup after the procedure. If I consult with you, would you be able to accommodate a reasonable number of sessions so that I can receive the treatment without any issues before my scheduled appointment? Please let me know, experienced practitioners!
