Parabens? No thanks!

  • There are no restrictions on the use
    of parabens in cosmetics in Canada

  • Parabens easily penetrate the skin. (1)

  • They are suspected of interfering with hormone function (endocrine disruption)(2)

  • Parabens may also interfere with male reproductive functions.(3)

  • Parabens in foods are metabolized when eaten, making them less strongly estrogenic.(4) In contrast, when applied to the skin and absorbed into the body, parabens in cosmetics bypass the metabolic process and enter the blood stream and body organs intact.(5)

In an American study, parabens have been detected in human breast cancer tissues, suggesting a possible association between parabens in cosmetics and cancer.(6)

Studies conducted by the U.S. Centers for Disease Control and Prevention (CDC) did find four different parabens in human urine samples, indicating exposure despite the very low levels in products.(7)
