Since frown line Botox is so popular, I can do it without fear, right?

Due to a bad habit of leaning my head forward toward the monitor and furrowing my brow whenever I concentrate on work, a hardened mark has formed right in the center of my forehead, looking as if someone had pressed their fingernail into it. It is so stressful that I look grumpy and angry every time I look in the mirror, so I want to tighten the muscles before it gets any deeper. I heard that frown line Botox is so popular that I can just get it done during my lunch break, but I am nervous because I read reviews saying that even a slight misplacement of the injection site can cause ptosis (drooping eyelids) and cause months of suffering. Please share your experience regarding how many days it takes for the squinting to completely subside and for the feeling of heaviness in my eyebrows to last, and how long the heaviness lasts.
