ALLERGEN METALS IN COSMETICS 321
JOURNAL OF COSMETIC SCIENCE 322 It should be highlighted that in the fi rst step of hazard identifi cation, determination of the intrinsic factors that may produce potential risk to human health should be consid- ered (1). Therefore, although removal of heavy metals from personal care products after manufacturing is not possible, careful selection of the raw material can improve the qual- ity of the products (15). Moreover, postmarketing vigilance is very important to protect public health, although the regulation on cosmetovigilance system is handled differently in many countries (27). Finally, it must be emphasized that contact dermatitis caused by cosmetics may be due to metal content therefore, to assess the safety of the fi nished products, routine monitoring of allergen metal content is crucial.
