Botox Inquiry

Hello. I am a man who is under a lot of stress because of my flat forehead.

My forehead has absolutely no volume, so my face looks very flat from the side. I've always covered it with my bangs, but now I want to try a style that exposes my forehead.

Honestly, I am hesitant about fillers because I am afraid of side effects or the foreign body sensation.

Will there be a foreign body sensation?

So, I'm curious: is it possible to improve the volume of a flat forehead with just a Botox treatment? Or is Botox used simply to smooth out wrinkles? I want to improve it naturally without it looking too obvious. Are there any men out there who have received Botox injections for a flat forehead like me? I would appreciate honest reviews from those who have experienced this.
