My appearance looks a little different after forehead Botox. Is this normal?

I received forehead Botox for the first time, and I am satisfied because my wrinkles definitely seem to have decreased. However, there are some aspects that are a bit different from what I expected, so I am writing this post to ask about them.

I tend to tense my forehead a lot, so I got Botox around my forehead and eyebrows. After about a week, I noticed that horizontal wrinkles on my forehead had almost completely disappeared. However, strangely enough, my facial expression looks a bit sharper and seems to look a bit angry compared to before.

In particular, the middle part of my eyebrows seems to be drooping slightly, and when I take photos, my expression feels stiffer than usual, so I wonder if I'm being too sensitive.

I've heard that getting Botox can reduce muscle movement and change your eyebrow shape or overall impression. Has anyone actually experienced this?

I am wondering if it will return to a natural state over time even if it feels awkward at first, or if the dosage or injection site needs to be adjusted for the next procedure. I want to reduce wrinkles but do not want my overall appearance to change, so I am concerned about how to approach the consultation for my next treatment.
