Paraben is a chemical compound made by scientists to help cosmetic and skincare products extend their shelf life. What is so bad about them? Parabens can act like the hormone estrogen in the body and disrupt the normal function of hormone systems affecting male and female reproductive system functioning, reproductive development, fertility, and birth outcomes. Parabens can also interfere with the production of hormones. And if that was not scary enough, the skin can get brittle, cracked, painful, swollen, develop rashes.
