I am planning to get Botox for the first time and have many questions.

Lately, whenever I look in the mirror, the wrinkles on my forehead and between my eyebrows seem deeper than before.
I am seriously considering Botox.
People around me say that if you try it once, it is easy to manage, and
I became interested because I heard it naturally softens the impression.
Now that I'm actually trying to look into it, I have so many questions.

Looking at online reviews, there are many people who are satisfied with the wrinkle improvement effects after Botox treatment, whereas
There are also reviews saying that the change wasn't as big as expected.
I would like to know what the difference is.
Do the results vary because the products or treatment methods used differ from hospital to hospital?
Or I am curious if there is a significant individual difference.

I would also like to know if the only benefit of Botox is simply wrinkle improvement.
I heard that this procedure is also frequently performed on other areas, such as the jaw muscles or trapezius muscles.
I'm also curious about how the expected effects differ for each.
I didn't want my face to look too stiff.
I consider the degree of natural change to be the most important.

And how long does it usually last?
I would also like to know if there are any special precautions I should take if it is my first time.
Is it possible to resume daily life immediately after the procedure, and things like exercise or drinking?
I would like to hear from those with experience about how many days I should avoid it.
