Roxy, I don't know of any magazines that fit what you're looking for, but just wanted to say that your daughter sounds like an awesome kid, and she's lucky to have your guidance.

Maybe another approach would be to look for magazines that are specific to her interests. For example, if SI for Women was still in publication, I'd recommend it. Amid ads for cosmetics and fashion (and women-specific sports equipment!), it also had articles about women who worked hard to achieve their goals, some of them even as a team! If there is a specific sport that she likes, there is probably a magazine for it. If she is interested in social justice issues, there are many magazines that focus on a range of those issues. I don't think they need to be age-specific. Nurturing her interests will go a long way towards building her self-confidence in the long term.

As for makeup -- when I was about that age my mother took me to a dept. store makeup counter to help me get ready for a piano recital. I was too clueless and awkward to figure it out through magazines (I had Sassy too. Didn't help ). It was invaluable to have someone show me how to apply it, and to walk away with stuff that worked for my complexion, that I was comfortable wearing. I don't think experimenting with drug store brands would have saved money at that stage, since I had no idea what I was doing with blending and colors and probably would have wasted a lot of money buying stuff that didn't work for me.
