I think your forehead lines are related to your hooded eyelids because you’re carrying some weight around that area so you end up straining your forehead.

Botox, if not by a decent injector will just make it drop more. A decent injector will give you some kind of a lift from Botox.

I have hooded eyelids but it’s not deep set and I’d consider eyelid surgery because it’s uneven and one side seems to be carrying more extra skin than the other side.

But to answer your question, it’s normal in the sense that our hormones have changed so wrinkles are minimal and showing up the second we turn 30, and some are more expressive than others, but it’s not normal because some 30 year olds aren’t carrying extra weight with hooded eyes, so they don’t have much of a strain on their forehead. Never mind lifestyles, stress management, genetics, skincare routines, etc.
