Before the Industrial Revolution, people used natural plant oils and products for beauty. Today in our mass market and commercialized society, cosmetic products are largely composed of a complex mixture of chemical ingredients. These synthetic chemicals have traditionally been viewed as innovations. Many of these chemicals became available from the discovery of oil, tar, and gasoline and are refined or developed from these petroleum products. The very same petroleum products that are being burned by automobiles. But our skin is the largest organ system in our body, and our skin is commonly used to absorb pharmacologic drugs in the form of drug patches. As a consequence, synthetic chemicals that your body would never have been exposed to in a natural environment are now being applied and absorbed through the skin with unknown long-term consequences to our health, mind, body, and spirit.
