Is Botox worth it?

Hi

I know it is not a good time to go out and get myself a Botox shot. I’m not planning to do that anyways. I’m just being genuinely curious about get it. I saw on Groupon, there’s a several good deals on get a Botox shot. So, I’m 31 and I have a bit of wrinkles at the corners of my eyes which bothers me a bit. Have anyone done that? Is it worth it?
