When is wrinkle Botox treatment effective?

I want to try wrinkle Botox, but usually

It's a procedure that prevents muscles from moving, you know.

If you say you are getting Botox for frown lines, perhaps already

If you have slightly deep frown lines, wrinkle Botox

Even if I undergo the procedure, will I not see much effect?

Since it's my first time, I'm curious about the pain, and whether it's domestic or German, etc.

I'm curious what the difference is. If I use a domestic product, the resistance...

I heard that resistance develops, but I wonder if the German ones don't develop any at all.

There is a price difference, so I am also wondering which one would be better.

And all at once, wrinkle Botox for the glabella, forehead, eyebrows, etc.

I'd like to do it together with everyone. Is that possible?

Please also let me know the recommended frequency for receiving this.
