Heavy Metals Concentration in Facial Cosmetics

Heavy metals impurities in cosmetic products are common due to their natural abundance. However, they should be kept to a minimum wherever technically feasible. Most people, specially females, use cosmetic and their ingredients on a daily basis. Although human external contact with a substance rarely results in its penetration through the skin and significant systemic exposure, cosmetics produce local (skin, eye) exposure and are used in the oral cavity, on the face, lips, eyes and mucosa. Therefore, human systemic exposure to their ingredients can rarely be completely excluded.
