Is there a big difference between before and after getting Botox?

Since Botox is such a popular procedure, I am interested, but

I've never actually been hit, so I have a lot of questions.

People around me say that if you get hit once, you'll understand why everyone takes it.

I am curious to know how much of a difference there actually is.

It's not because of my square jaw, but

I am looking into this because of the forehead wrinkles or frown lines that appear when I make facial expressions.

My wrinkles aren't very deep yet, but

I've heard that it's better to manage it in advance, so I'm considering it.

Is the effect of Botox more certain than expected?

Is the difference noticeable even when looking at the photos?

Or I'm curious if it's closer to a change only you know.

What else do you think are the advantages of Botox?

In addition to the fact that the procedure time is short and recovery is fast

I’d like to hear if there were any parts you liked after receiving it in person.

I am also curious about when the effects will appear.

I wonder if things change immediately after getting hit.

Or I also want to know if it takes a few days to see changes.

And from the perspective of someone meeting it for the first time

I'm also curious about the extent of the pain or discomfort.

If anyone has received Botox...

How much of a difference there was before and after the procedure

What were the effects and advantages?

How long did the maintenance last?

Please honestly share your actual satisfaction level.

I'm debating whether or not to get it, so I'm really curious about your experiences.
