Heavy metal impurities: The most frequent heavy metals present in cosmetic products are cadmium (Cd), mercury (Hg), lead (Pb), chromium (Cr), nickel (Ni), and copper (Cu). These heavy metals are found in lipstick, talcum, shampoo, cream and eyeliner.

Possible adverse effect on health:

Fragrances and preservatives are the two most important clinically relevant allergens founds in beauty products. Fragrant compounds can penetrate epithelial and absorbed into bloodstream and distributed to other body organs. Fragrance mediated allergic reaction produces side effects such as skin sensitivity, dermatitis, asthma and migraine. Allergic contact dermatitis is an inflammatory skin disease with common symptoms of erythema and swelling and if exposure remain continues it will leads to allergic lesion on skin and subsequently to skin cancer. Heavy metals are present in trace amounts in beauty products. And even in laser concentration these toxic compounds can cause internal body organ damage, in animals and humans. Cadmiumis one of the most toxic metal ions in environment, and it can be found in air, food, and water. Cd ions are absorbed by most tissues of the body and become concentrated mainly in liver and kidneys. The most dangerous characteristic of cadmium is that it accumulates throughout a lifetime. Chronic human exposure to Cd results in renal dysfunction, anemia, hepatic dysfunction, osteo toxicities, and cancer in multiple organs, potentially including the kidneys. Lead poisoning has been a recognized health hazard for more than 2,000 years. Characteristic features of lead toxicity, including anemia, colic, neuropathy, nephropathy, sterility and coma. Exposure to low-levels of lead has also been associated with behavioral abnormalities, learning impairment, decreased hearing, and impaired cognitive functions in humans and in experimental animals. Mercury-containing products are poisonous and induce severe side-effects, which have been demonstrated in multiple case studies.  Local effects include burning sensation of the skin, contact dermatitis, nail discoloration, and paradoxically, blue/black skin pigmentation.
