My daughter just turned 14 and she's been anti-make-up so I haven't had to deal with the issue really.  However, since she has break-outs I feel it might her feel better to wear a bit.  SO it looks natural and hopefully won't bother her skin more I took her to Bare Essentials for a natural look. 

I took my daughter to the Clinique counter and asked them to show her how to do a natural look. We then went to the drugstore and purchased a lower priced brand but she knew how to apply it and how much to put on after seeing it done by a professional!
