How should I schedule the application cycle for melasma skin boosters?

I am leaving an inquiry regarding the melasma skin booster cycle.

I have an important photoshoot scheduled in two months, so I would like my skin tone to look at least a little more even before then, but I don't know when to start. I have pigmentation on my cheekbones that looks like melasma, and since my skin is dry, that area looks even duller when I apply makeup.

I understand that a melasma skin booster isn't a procedure that immediately removes the pigmentation itself, but I'm wondering if it helps improve skin condition so that makeup doesn't cake as much and the skin looks less dry and dull.

How often should melasma skin boosters be administered, and if I have an important schedule, would it be best to start with some buffer time?

Since it's my first time, I'm worried about how long the redness or marks will last lol. I'd also like to know if you can schedule the number of sessions or the intervals based on the dates I mention during the consultation.
