When looking at the ingredients list on a product, there are many things to take into consideration. If the product was designed by a professional, it's likely that it will contain ingredients that are approved by the FDA. However, there are also many more ingredients to consider when shopping for lightening products. This page will provide you with a good starting point. I have included a summary of each ingredient in the products on this page. 1. Ingredients in Products That Actually Work 2. Supplements and Products That Do Not Work 3. Natural Products 4. Natural and Synthetic Ingredients 5. What Do You See When You View Products on this Page? All products in this page, including products that don't work, are reviewed on an organic, unallergenic and naturalistic basis. I believe that this is the best way to evaluate the effectiveness of the products in the market and that all products should be evaluated on this basis. However, we can't evaluate everything on this basis. Therefore, I will not list ingredients that I don't know about (such as those that are not natural). For products that I do know about, I list those that I use as a reference for the product.
