The Chemistry of Beauty 2
Cosmetic Appeal

Cosmetics are used to enhance one's appearance by adding color or redefining facial features.  While they are used all over the globe, they have not always been safe, and in fact, some are still linked to dermatitis, allergic reactions, birth defects, blindness and even death.  Now a regulated industry in the western world, cosmetics are tested frequently to maintain safety.  This is important, as cosmetics are a 19 billion dollar business in the United States alone.
