Let's start with "Dirty Words". If a product says fragrance in the list of ingredients I try to stay away. I have read that one word can account for 500 different chemicals! Now I know we all LOVE the smells of our products, but a much safer route would be look for products scented with essential oils instead. I follow these rules for all of mine, Matt's, and Sophia's products. Again, as with everything else I do the best I can and by no means am perfect with this.
Other "Dirty words" I look for are: Phthalates (tha-lates), Parabens, Sodium Lauryl/Laureth Sulfates, Formaldehyde. You can google each of these to see the effects on our bodies. This post would be too long if I went into detail. Bottom line is they all cause cancer. And it is especially important for women to watch what is going into our bodies as they are finding hundreds of chemicals in the cord blood of new babies. Our babies are being born already toxic! That is scary!
I like to do my shopping as quickly as possible and don't like to sit and read a bunch of ingredient labels, especially on nail polish! That print is SO small you have to have a magnifying glass. So I do my homework before hand and know what companies are producing responsible products. Check out http://www.safecosmetics.org/ to start your own research.
Target, Sephora, and Kroger are great places to start and of course Whole Foods to those who are close to one. Also, I do a lot of my shopping online at http://www.vitacost.com/ and go to the organic section.
Our skin is our largest organ and everything we put on it absorbs into our bodies. So we should be just as concerned as what we put on our bodies as we are about what we put in our bodies!
