Well yes, your young age and this fact makes your chances quite good to grow out of it. For my part I discovered a change in my acne when I gew out of my teenager acne and into adult acne. Suddenly the pimples were located only around my mouth and jawline and were obiously linked to my menstrual cycle and more cystic. My forehead was covered in zits during teenager acne, but absolutely clear since my early twenties.
WOW, that is exactly what happened to me too and I'm male. When I was teen I had horrible acne on my forehead and nose and now I don't get acne on my forehead and nose unless I really irritate those areas. My trouble areas now are mainly sides of my jaw/mouth and inner cheek areas..
