Is there anything I need to prepare before getting forehead Botox?

Hello. I have booked my first forehead Botox appointment for next week, and I am writing to ask if there is anything I need to prepare in advance. Since it is my first time getting the procedure, it might not be a big deal, but I am feeling quite anxious about it.

I am wondering if there are any foods or exercises I should avoid the day before or on the day of getting forehead Botox. I usually exercise regularly, so I would like to know if it is advisable to rest before and after the procedure. I am also unsure about minor details, such as whether I can visit with makeup on or if I should wash my face at the clinic.

I am also wondering if it is okay to go to work or have an appointment immediately after the procedure. I would like to know if anyone experienced long-lasting injection marks or severe redness, and if it is advisable to leave a few days of buffer time if I have an important schedule.

Since this is my first time, I have many concerns, but I would like to prepare by referring to the experiences of those who have received forehead Botox. Please feel free to share any tips or things you wish you had known before the procedure that were helpful.
