I did it for me, I'm 30, and although, I do not smoke or worship the sun, my forehead still had a huge deep wrinkle all the way across it. The saying, "don't make that face, or it will stay like that" popped into my head, as my mother would tell me that, growing up.
I have always spoke with my facial expressions. And it had taken it's toll. My husband didn't want me to get anything done, because he was afraid of my face looking unnatural or "too tight", but he actually really likes it now. It literally took 10 years off my face.
My makeup goes on smoother, and even my 11 year old, who can be very blunt sometimes, said "that stuff, really made your line go away"(as she pointed to my forehead). Out of the mouth of babes:) I LOVE IT! IT TURNED OUT PERFECT!!!!!!!!!!!!
