Hello, let me come directly to the point. This product you know I was used to have this when I was in my tenth standard. I bought this through one of my closest friend as he recommended me that this product is awesome. Okay first let me tell what is meant by carcinogen it is that ability of a product that may cause you cancer ( skin cancer, ) . When I applied it on my face it popped up with a good fair colour but as you know it is also sweat resistant so from this the major problem start. Sweating is a natural mammal tendency and if dare to stop it then this may lead to many severe skin problems. I hope you must have understood why I am not letting you to buy such a kind of product. Thank you guys stay tuned with me because I will try my very best to bring such informative concerns to my society.
