I have recently seen an article in a magazine which says that even the mineral cosmetic contains some chemical which are harmful for your skin. I have a huge collection of mineral cosmetic make up and use it regularly on my face. So I want to know is this true and if yes then what kind of chemical they contain and to which extent they are harmful to our skin? Also tell me that every product has chemicals or only few of them so that I can replace them with non chemical productsâ¦
