The concept of natural cosmetics is associated with the total absence of ""synthetic"" components, mineral and petroleum derivatives. However, this is often a misleading simplification that reassures the consumer about the quality of the product as we have now been accustomed to evaluating only the Ingredient List, within the limit of the technical understanding of the formula. The situation is, however, much more complex and deserves a reflection: it has become common belief that everything that is natural is also healthy. Secondly, it is important to understand that even natural raw materials that are undoubtedly effective often pollute much more than a silicon or synthetic ingredient."
