Are there any procedures other than Botox for frown lines?

I have deep vertical wrinkles between my eyebrows.

I wear glasses because my eyesight is poor, and I used to have a job where I stared at a computer all day long.

My vision was getting blurry, so I kept frowning while working, and before I knew it, two deep wrinkles had formed.

The line on the left is thicker, so it stands out particularly.

I don't really frown or anything; the thick vertical lines are noticeable even when I'm just standing still, so I want to get a procedure. However, I heard that Botox has temporary effects and looks unnatural.

Is there a procedure that is more natural-looking than Botox and effective for wrinkle improvement?

Is it impossible to get rid of wrinkles once they have formed?

Then, which procedure has the longest-lasting effects?

If anyone knows, please give me some advice.
