Independent laboratory tests have found that many of the top lipstick brands contain lead. It’s a scary fact, but many products sold in the cosmetic aisle, exempt from FDA oversight, are similarly tainted. Many teens and young adults are deciding that it’s more environmental, economical, and healthy to make or buy toxic-free cosmetics. At web sites like MakeYourCosmetics.com, women trade easy-to-make recipes as alternatives to products like mouthwash, acne solutions, and lip gloss. You can find most of these ingredients in your kitchen, your backyard, or at any number of local health-food stores. The more complex recipes sometimes call for mail-order ingredients, but if you look hard enough you can find everything you could possibly need right here in the Bay Area.
