Adolescent Exposures to Cosmetic Chemicals of Concern
By Rebecca Sutton, Ph.D., Staff Scientist, September 2008

The 20 teens we tested had an average of 13 hormone-altering cosmetics chemicals in their bodies.
Laboratory tests reveal adolescent girls across America are contaminated with chemicals commonly used in cosmetics and body care products. Environmental Working Group (EWG) detected 16 chemicals from 4 chemical families - phthalates, triclosan, parabens, and musks - in blood and urine samples from 20 teen girls aged 14-19. Studies link these chemicals to potential health effects including cancer and hormone disruption. These tests feature first-ever exposure data for parabens in teens, and indicate that young women are widely exposed to this common class of cosmetic preservatives, with 2 parabens, methylparaben and propylparaben, detected in every single girl tested.

This work represents the first focused look at teen exposures to chemicals of concern in cosmetics, exposures that occur during a period of accelerated development. Adolescence encompasses maturation of the reproductive, immune, blood, and adrenal hormone systems, rapid bone growth associated with the adolescent "growth spurt," shifts in metabolism, and key changes to brain structure and function. Alterations in an array of sex hormones, present in the body at levels as low as one part per billion (ppb), or even one part per trillion (ppt), guide this transformation to adulthood. Emerging research suggests that teens may be particularly sensitive to exposures to trace levels of hormone-disrupting chemicals like the ones targeted in this study, given the cascade of closely interrelated hormonal signals orchestrating the transformation from childhood to adulthood.
What one girl has to say:
In Alex (Washington DC): 12 hormone-altering cosmetics chemicals. "It's frightening to learn about the many different kinds of toxic chemicals that can be found in my body. At the same time I would much rather be knowledgeable about my body's chemical makeup than uninformed; in this case, ignorance is NOT bliss."
