I'm curious about the effects of botox.

A friend of mine told me she got Botox injections around her forehead and eyes, and when I looked at her face, I noticed her wrinkles seemed to have faded a bit. So, I'm also concerned about the wrinkles between my eyebrows and around my eyes, so I'm researching Botox treatments. This is my first time getting Botox, so I'm unsure which area to start with. People around me say the effects are more natural than I thought, so I'm curious. I'm worried my facial expressions will look awkward. Is it okay to get Botox? I'd love to hear from someone who has actually experienced the effects!
