I have a question about how to improve forehead wrinkles.

At some point, horizontal lines began to appear on my forehead, and now even when I'm still, deep wrinkles form. My friends say it's because I use too many muscles when I frown, but even I think I look angry.

I'm still hesitant about the cost of plastic surgery, so I'm wondering if there's a simple way to recover. I looked it up and found that many people get Botox or fillers. What would be effective for deep wrinkles like mine?

I'm also worried that if I get the procedure, my forehead will feel too heavy or my facial expressions will look awkward. Please help.
I want to walk around with confidence.
