There is a good deal of confusion with regards to ingredients. John, my business partner is a lot better at this than me. When we are trying to create a new product, especially one with colour ( spelled with an ou in Canada ) it can get really confusing. Finding colours that are both natural and FDA approved is a tough combination. Many colours that are FDA approved are pretty questionable. One great resource for searching out ingredients is a website called "skin deep" here is the link : http://www.ewg.org/skindeep/
Another interesting read is a book that has been around a while called " There's Lead in Your Lipstick"
