Will Botox be effective between the eyebrows?

At some point, I noticed thin wrinkles forming between my eyebrows and on my forehead. Also, I have a habit of squinting while looking at my phone; they say I keep tensing the space between my eyebrows.

I didn't realize I was tensing my forehead, but a friend told me to straighten it out because it causes wrinkles. Since then, I've been consciously trying to straighten it out, but it's not working well.

Now, thin wrinkles are visible on my forehead as well, because I have developed a habit of constantly raising my eyebrows.

I really dislike how deep the wrinkles between my eyebrows become, so I want to get Botox as soon as possible, but I'm also worried about the side effects.

When celebrities come out after getting Botox, their faces look bulging and it's so obvious, and when the Botox wears off, their faces turn bumpy and unsightly.

You recommended Botox for my glabella and forehead; will it be effective?
