I really use lots of cosmetics on my face and skin. Yesterday I was reading a magazine and I read sentence over there where it was written that cosmetics contain the Diazolidinyle urea. So my question here is that what are the side effects of the Diazolidinyle urea that are present in the cosmetics and the shampoos? And is there any alternative for the people who donât want to use the Diazolidinyle urea containing cosmetics and shampoos? Can you also give me the list of some of the cosmetics that contain the Diazolidinyle urea?
