Should you consider the switch to all-natural cosmetics? Here's what you need to know.First, department store make-up counters are known to use engaging promotional ploys. Big-time brand names command high prices and compete with big promises.Enter the "naturals" to health food stores and the Internet. You'll recognize them by words like "organic" and "holistic." Are these features worth it in cosmetics? Or is it hype?According to Dr. Roberta Palestine, who did her residency in dermatology at the Mayo Clinic, "It really is marketing hype. Natural isn't always better. Synthetic isn't necessarily worse.""Poison ivy is natural, but that certainly doesn't make it good," Palestine adds. "A chemical is a chemical," she says, "what matters is your skin type."If you're prone to acne, learn to read labels. If your skin is more mature, you need moisturizing ingredients," Palestine tells consumers. Others need to prevent allergies.She points out that "hypoallergenic" means it is free of offending ingredients. It does not mean a product will prevent break-outs or acne.
