I'm 37 and decided to try Botox on my frown lines in between the eyes because I catch myself squinting in a strong frown all the time...I do it while I work, I do it when I'm discussing something important, I even do it in my sleep! Sometimes I wake up with a sore forehead with this troubled squint. I just can't stop myself from doing it. I wanted to try Botox not necessarily for cosmetic...
