Almost all women of age are using a variety of makeup and skin care products to keep themselves young and healthy, which is as common as we eat, but the sudden questioning of the quality of food has awakened many people. What is “eaten” through the tiny pores of the skin? And is it good or bad? Bad cosmetics damage not only the skin, but also the whole body. Push open two doors to see the truth about cosmetic poisoning. The first door: At the door of the dermatology clinic, we see a long line of people with erythema, papules, blisters, pigmentation and other symptoms on their skin, many of whom have skin abnormalities due to long-term use of certain cosmetics. Expert’s words: Currently in the dermatology clinic, we are encountering more and more cases of skin lesions such as erythema, papules, blisters and pigmentation caused by improper use of cosmetics, the most common of which are allergic reactions to contact dermatitis and irritant dermatitis. The second door: the outpatient clinic is mostly in consultation about cosmetic poisoning. They express deep anxiety over some cosmetics they have used. Expert’s words: The poisoning caused by cosmetics is mainly reflected in the excessive content of mercury and lead in cosmetics. The ingredients that really have whitening and spot-removal effects, such as arbutin and vitamin C, can only work slowly, while the whitening or spot-removal effects of “mercury-exceeding” products are fast, because these ingredients can “eat the skin alive”, causing peeling and making the skin The skin looks white. The “excessive mercury” products can destroy the normal physiological structure of the skin and eventually produce abnormal skin pigmentation and “dark skin”, which can even damage the nervous, digestive and endocrine systems and lead to internal organ damage. Therefore, it is important to pay enough attention to products that are advertised as “fast spot removal”. When you see or feel these problems on your skin ……, you may be a long-term user of cosmetics with excessive lead and mercury content if the following conditions appear on your skin: dull skin, increased stratum corneum, spots on the skin and grayish-black color; easy to grow deep acne; hot and swollen feeling when exposed to the sun, and deepening of pigmentation, recurring over the years; The spots are mostly on the cheeks, chin and forehead, especially on the cheekbones, which are the deepest and most serious. If the following conditions appear on the skin, you may be a long-term user of hormone-containing cosmetics: thinning of the skin epidermis; appearance of dilated capillaries (red blood cells) and recurrent small papules; loss of the original skin color on the face and formation of red patches; appearance of burning lesions, dryness and itching, rough skin with thinness, scaling and pigmentation; formation of hormone dependence, or even hormonal dermatitis. What cosmetic ingredients are the main causes of skin lesions? The most important is the whitening agent, because the main components that produce the effect are lead and mercury. These ingredients can have a cosmetic effect at first, but afterwards they cause hyperpigmentation and are more difficult to treat. There have been many cases of cosmetic poisoning in Japan and abroad, especially in Japan, where there are many reports of mercury poisoning caused by cosmetic products. Does lead and mercury poisoning caused by cosmetics damage not only the skin but also the internal organs of the body? Yes, it does. Lead and mercury can cause damage to internal organs by absorption of cosmetics through the skin. What are the symptoms of mercury poisoning? The main symptoms are personality change, anemia, irritability, gum inflammation, etc. Some people may also show signs of neurosis, such as poor sleep and memory loss. Must cosmetic poisoning be the result of long-term use? This is true in most cases, because toxins in cosmetics are latent in the body and absorption by the skin is a slow process, and only when toxins accumulate to a certain level can they cause poisoning. However, if the cosmetics are of poor quality and contain too much lead and mercury, symptoms of poisoning may also appear in a short period of time. What symptoms should be tested for poisoning? Cosmetic poisoning should be considered when you have trouble sleeping, irritability, menstrual disorders, and anemia in laboratory tests. What is the most common way to detect poisoning in humans nowadays? Can mercury poisoning in humans be cured? At present, we mainly detect the poisoning of human body by urine test. With timely treatment, it can be cured after a period of time. Can I self-regulate through diet after poisoning? Self-regulation is very difficult and medical treatment is necessary. Therefore, it is necessary to go to a hospital to seek help from a doctor. What should we do in our daily life to avoid problems? It is very simple: use only cosmetics made by regular manufacturers. The whitening cosmetics basically contain lead and mercury, but as long as they do not exceed the limit, they will not cause poisoning. The content of lead and mercury in the products of regular manufacturers is strictly measured and controlled within the allowed standards, while the quality of products from some informal manufacturers is difficult to guarantee. Can our skin really be poisoned? It is certain that the skin itself is an absorption organ. It can absorb foreign substances through the gaps between the stratum corneum and cells and sweat gland pores and hair follicles, such as cosmetics and topical drugs that we usually use, which are absorbed through the skin to nourish the skin and deep tissue. However, it is not absorbed as directly as the respiratory system and digestive system, so skin poisoning is often a long process, and mercury and lead poisoning are the most common. What are the specific symptoms of skin poisoning in general? What people generally call skin poisoning is only some local direct skin damage, such as erythema, papule, blister, pigmentation, etc. This belongs to external skin damage; cosmetics are used by the skin to treat the skin. There are three kinds of adverse reactions after cosmetics are absorbed by the skin: 1. allergic reactions, which are related to individual differences. 2. 2. Cosmetics contain irritating substances, which can cause adverse reactions no matter who uses them, or under certain dosage conditions, such as some acidic substances are harmless when diluted; while high concentrations can cause burns. This is irritant contact dermatitis. Both of these adverse reactions tend to occur within one to seven days after using the cosmetic in question. 3. Cosmetics contain harmful additives, which may not show any symptoms at first, but manifest themselves when accumulated to a certain extent, such as dry skin, atrophy, pigmentation, thickened hair, dilated pores, and even lead to chronic mossy changes. Another major category is internal organism damage, such as the use of “toxic” cosmetics for years and years, when the accumulation of harmful substances to a certain extent will cause damage to the whole body, especially the liver, kidneys and other organs. How should these problems be treated? For the treatment of contact dermatitis and irritant dermatitis, the first thing is to stop using all cosmetics, even medicines that you think are effective should be stopped. At this point, you must go to the hospital for an examination to clarify the cause of the allergy, and then treat the symptoms. If you do not have very obvious symptoms, but slowly develop personality changes, anemia, irritability, inflammation of gums, neurological weakness, and decreased responsiveness, you should seriously consider whether it is related to the cosmetics you are using, and promptly go to the hospital for laboratory tests and targeted treatment.
