If I want to get Botox before an important event, should I leave a few weeks of buffer time?

I have a lot of photos to take next month, so I'm thinking about getting Botox.

I usually don't pay much attention to it, but when I zoom in on photos, the wrinkles that form when I make facial expressions look deeper than I thought, so I suddenly feel the urge to take better care of them haha.

The problem is that I have never had Botox.

Since it's my first time, I'm not sure how my face will react, and I can't decide on a date because I'm worried about doing it right before my schedule and my expression looking awkward.

I heard that the effects of Botox don't appear immediately after the procedure but take a few days to show. How far in advance should I get it done relative to an important event?

I am also wondering if about a week is sufficient, or if it would be more reassuring to leave at least two weeks.

Is it possible to feel a little awkward for the first few days, but then it becomes natural over time?

I'd rather it settle down a bit and look natural on an important day, haha.

I am also wondering if there is a possibility of bruising or small injection marks after getting Botox.

I also want to know how many days it takes for such marks to be well covered with makeup.

I am also wondering if I can wear makeup and go about my daily life as usual starting the day after the procedure.

For those of you who have received Botox for the first time before an important photoshoot or trip, how far in advance did you get it done?

Since it's my first time, I think it would be better to schedule it a little earlier rather than too close.

I would also like to know, based on your actual experience, when the effects of Botox felt the most natural.

I am also curious if there are people who liked it better about a week or two after the procedure than immediately after.

I'm curious to know how those of you getting Botox for the first time before an important event can realistically schedule your time haha.
