99 Ingredients You Don't Want In Your Skincare Products.

Well, here it is, a very comprehensive list of harmful chemicals currently used in skincare, hair care, makeup, and fragrances (Don't be fooled though, there are many, many more that aren't on this list). Use this list anytime you buy a beauty product. And for goodness sake, don’t keep it secret, please feel free to copy it and give it to your family members and friends.
