2, lead, mercury: it also has the effect of whitening and removing spots.
It is also added to lipstick, lip gloss, nail polish, etc., which plays a role in precipitation and coloring. Long-term use will thicken the stratum corneum and directly enter the digestive organs and internal organs. Although the skin looks very white for a while, it will precipitate melanin under the skin for a long time, forming lead-mercury spots or lead-mercury poisoning, which is difficult to remove.
3, methanol: often used as an additive ingredient of spices into skin care products, toxic.
4, chromium, neodymium: chromium can cause allergic dermatitis or eczema, the course of disease is long, long and not healed. Neodymium is very irritating to eyes and mucous membranes, and moderately irritating to skin. Inhalation can also lead to pulmonary embolism and liver damage. According to the relevant provisions of China's Hygienic Standard for Cosmetics (GB79 16), cosmetics should not contain prohibited substances such as chromium and neodymium. Some time ago, chromium and neodymium were found in some products of SK ⅱ, Estee Lauder, Lancome, Dior and Clinique.
5. Soap alkali component: It plays the role of removing oil stains and is often added to facial cleanser. However, it will destroy the natural weak acid protective film of the skin (indoor fumigation with vinegar means sterilization in acidic environment), making it easier for bacteria and mites to grow and reproduce. Commonly used alkaline facial cleanser will accelerate skin aging.
6. Alcohol: It can astringe pores, diminish inflammation and sterilize, but it is easy to make skin dry and wrinkle, accelerate protein degeneration of skin and promote aging.
7. Mineral oil (paraffin oil), vaseline, lanolin, etc.: Cover fine wrinkles and lock moisture. However, it will block pores and make the skin unable to breathe, resulting in dull skin and large pores. At the same time, excrement in pores is not easy to be discharged, leading to acne, acne and folliculitis. At the same time, these ingredients have strong ability to absorb ultraviolet rays and are easy to cause skin spots. Scientific research has found that mineral oil can cause cancer.
8. Artificial saccharin. It is extracted from coal tar and is a flavoring agent in cosmetics, which is reported to easily lead to cancer.
9. Pigments, preservatives and spices: Most of them are synthetic products, such as coal tar synthetic spices and aldehyde series synthetic spices. Among coal tar pigments, there are nitroso dyes and nitro dyes, which are very harmful to human body, and once they enter human body, the harm is even greater.
The main component of preservatives put into cosmetics is formaldehyde, which will pollute indoor air when released.
Hair dye is an oxidized dye, including more than 20 chemical components, about half of which can induce cancer.
10, Hormone: Hormone can be used in cosmetics to temporarily remove wrinkles, make the face full, moist, elastic and shiny, inhibit and relieve the skin, and can make the skin not repel, relieve itching and relieve pain after injury, so it is widely used in "special effects". However, hormone is an easy-to-oxidize chemical component. People who often use hormone products will get darker and darker by the sun in summer, and finally it is difficult to take it off. This is because cosmetics are oxidized under sunlight and blocked by pigment cells, and the color becomes darker and darker, and it is deposited on the epidermis. It is often mistaken for "chloasma". Products such as hormone cosmetics or skin cream are often used, and the skin is stimulated for a long time, which is easy to make the skin immune function hyperactive, leading to the decline of the skin's autoimmune function, forming sensitive skin and allergic skin.
