When we use products daily that are known carcinogens, hormone disruptors and contain heavy metals we are asking for trouble. It's pretty basic, if you poison yourself long enough, the body is going to suffer.
Cleaning up takes research and change. Using resource centers like Skin Deep, www.ewg.org/skindeep/, is a big help. EWG's Skin Deep is a cosmetics data base of over 70,000 products. Their focus is shampoo, sunscreen, moisturizers, make up, facial cleansers and foundation. Each is rated in cleanliness from 1-10. It is a quick and simple way to know how much toxicity you add to your body's workload every day.
Be sure to check ratings for all the products you buy from any one product line as they can vary greatly. Even the cleanest brands will carry items that are outside of their focus just to accommodate different types of buyers. That mean, buying solely by brand does not always work.
If you are going to clean up your lifestyle there are a couple good rules to follow. First of all, if it comes with a coupon from a major corporation, it is likely not clean. Secondly, if you cannot pronounce the names of ingredients, they are also not likely your first choice for cleanliness.
