Is Botox really the best for frown lines and nasolabial folds?

It seems like I'm not the only one worried about the space between my eyebrows and nasolabial folds.

I am particularly worried because the furrows between my eyebrows are deep.

When I was working, I used to work with my face practically buried in the monitor while frowning, and after doing that for such a long time, a valley really did form in the middle of my forehead.

It bothers me so much because the furrow between my eyebrows is clearly visible even when I have a blank expression.

Is Botox really the quick fix for forehead wrinkles?

I really hate pain.

I would like the effects to be quick, so I am wondering if Botox is the best option.
