Sure, we know there are chemicals in cosmetics. We’re not sure our teenage daughters know though, and there they are, slathering glosses, lotions and assorted goos on their baby soft skin. It’s a concern for Jill Hughes, a Campolindo High senior, too. She not only makes her own cosmetics and beauty products – brown sugar body scrub, anyone? – she’s organizing a Teens for Safe Cosmetics workshop on Sept. 20 from 1 to 4 p.m. at St. Stephen’s Episcopal Church in Orinda. The free beauty fair is open to middle and high school girls, and it includes workshops on making your own bath salts and natural beauty products, as well as an intro to the “Dirty Dozen,” toxic chemicals that lurk in commonly used commercial products. Very cool. For details, drop her an e-mail.
