Makeup artist Bobbi Brown says she sees a trend of girls wearing more makeup at a younger age. "I used to reserve black eyeliner and a little bit of a smoky eye for 18-year-olds, but there are plenty of 15- and 16-year-old girls that wear it now," she says. "Ten years ago they would never, but almost every girl now wants black eyeliner."

Brown isn't against makeup on young teens if it's done the right way. "All girls are beautiful—what it takes is time," she says. "Find what makes you special." Then, use makeup to enhance that natural beauty.

Brown suggests looking for role models who are truly beautiful, like tennis champ Venus Williams, golf pro Morgan Pressel and Secretary of State Hillary Clinton.

"Strong is beautiful," she says. "Skinny is not."
