How should I schedule the Pico Toning cycle before an important event?

I am writing to ask how I should schedule my Pico Toning treatment before an important event. I have a photo shoot coming up in about two months, so I would like my skin tone to look at least a little bit clearer before then.

My whole face isn't super dark, but I have some fine pigmentation on my cheekbones and cheeks, so my skin looks a bit patchy in photos haha. I looked into Pico Toning, and it seems like it isn't a procedure that makes it disappear completely in just one session; I heard you have to get it repeated for a while??

So, if I start Pico Toning now, I am wondering how many sessions I can receive before my scheduled appointment. I am worried that my skin might become sensitive if I schedule the sessions too frequently, but I am also concerned that I won't notice much of a difference if I start too late. ㅠㅠㅠ

If redness or dryness may occur after Pico Toning, I would also like to know if it is advisable to avoid the procedure a few days before the photoshoot. If I mention my desired date during the consultation, would you be able to create a schedule that fits?
