[skin concerns] recommendations for 9 yr old

Beauty Tips For Body Care
My nine yr old daughter is getting mild pimples and blackheads on her nose. She is a show jumper, which means we are at the barn and in arenas a lot, where a ton of dust and dirt gets kicked up. She is also starting puberty early I think, because she is starting to get some underarm hair. I don't know which one is causing the breakouts, or maybe both.I'm unsure what she should be using and what kind of routine she should have. I'm worried that she may have sensitive skin because of her age, and she has had some mild eczema since she was a baby. (Never on her face, though)I'd appreciate some recommendations on what products I can buy for her, and what about some sort of wipes she can use right after she's done riding?
