Another major source of toxins are in COSMETICS. This site, skin deep is an amazing source of information about what is in your make up, shampoo, lotion, baby products, and what these chemicals have been proven to do to your body long term. It also give pages of alternative cosmetics to use that dont contain any of the crappy stuff. I found out my mascara and eyeliner contain propylparaben which is linked to developmental/reproductive toxicity, Endocrine disruption, and Allergies/immunotoxicity. awesome.
It's not like you're eating this stuff, what does it matter if you put it on your skin? YOUR SKIN IS YOUR LARGEST ORGAN, hello.
I know you can't be totally paranoid about everything, but why not be aware and choose an alternative that won't negatively affect your health?
