Wrinkle botox effect

I would like to inquire about the effectiveness of botox for wrinkles.

When I asked someone around me about it, they said they didn't know, but it had been quite a while since they started getting hit.

I guess I'm at an age where I should get botox for wrinkles...

The areas I'm most concerned about are the nasolabial folds and the wrinkles between the eyebrows.

Are these areas also effective when treated with wrinkle botox?

And please tell me how long wrinkle botox lasts and what types are available!
