Scientific evidence that cosmetics are harmful to health. The love of beauty is a woman's nature, and cosmetics are the closest partners of female friends. However, in any case, women should try to reduce the use of cosmetics. Let's look at the scientific evidence that cosmetics are harmful to health.
Scientific evidence that cosmetics are harmful to health 1 1. reasons:
1, cosmetics contain chemical components, but more or less there are harmful substances, which will irritate human skin. For example, depigmented cosmetic preparations contain toxic chemicals such as inorganic mercury salts and hydroquinone, which are potentially harmful to human body after long-term use.
2, some cosmetics, in order to highlight the effect of cosmetics, drugs such as antibiotics will be added, which will make the skin become very good for a period of time, but long-term use of the skin will produce dependence, causing inflammatory skin diseases on the face or other makeup parts.
3. In hot summer, most of the capillaries in the whole body are open, and the blood circulation in the whole body is accelerated, which will increase the absorption of harmful chemicals and easily poison cosmetics.
4, long-term lipstick will also affect the overall health. Lanolin and wax in lipstick have strong adsorbability, which often adsorb dust, bacteria, viruses and some heavy metal ions in the air on the oral mucosa, which not only increases the probability of causing allergies, but also easily brings lipstick and harmful substances attached to it into the oral cavity when drinking water and eating, which is harmful to the body.
Second, the solution:
1, makeup must be removed, and makeup removal is particularly important. It is necessary to take off makeup at night. Cosmetics attached to the skin for a long time will do great harm to the skin and easily lead to skin aging.
2, usually pay attention to grasp the degree of makeup, do not wear heavy makeup, makeup will affect permeability, skin will feel dull and itchy.
3. Try to choose mild and non-irritating cosmetics, and you won't be able to buy inferior cosmetics for a while.
Extended data
1. Cosmetics related to hair dyeing, perming, whitening and freckle removal, manicure, lip beauty and breast augmentation often contain a lot of chemicals, which are likely to cause harm, and need detailed consultation to understand the situation.
2. Choose high-quality cosmetics: First, pay attention to check whether the cosmetics have trademarks, production dates, manufacturers' names and hygiene license numbers.
Don't believe in advertisements, especially those that say they have magical effects, which may contain some chemicals with miraculous effects but huge side effects.
4. Allergy prevention: Before choosing a new, unfamiliar or never-used cosmetic, you should do a skin test first, such as a small skin test on the back of your hand to test whether you are allergic. You can only choose if there is no redness, itching and other reactions.
5. Pay attention to the shelf life: Cosmetics contain substances such as fat and protein, which are easy to deteriorate or be infected by bacteria after a long time.
6, pay attention to the details of use: different brands, different series, different types of cosmetics, do not mix, so as not to produce adverse reactions or bad smell.
Scientific evidence that cosmetics are harmful to health. Regular use of cosmetics is harmful to health. Richard burns, a British biochemist, warned that women who wear makeup every day modify their beautiful appearance, but they also inhale an average of about 2.3 kilograms of chemicals every year.
When women use cosmetics, chemicals enter the body through the skin and are absorbed by the body. In contrast, direct consumption of these chemicals may be less harmful to the human body.
If lipstick enters the mouth, its chemical components will be decomposed by enzymes in saliva and gastric juice. But if you put it in your mouth, the chemicals will enter the blood directly.
The appearance of some cancers may be related to people's extensive use of certain cosmetics. At the same time, some cosmetics may also cause irritation to the skin and even accelerate aging.

The Daily Mail reported that the dermatologist McLenna Alexis-Amen Necas of Yale University School of Medicine warned that using Halloween cosmetics may lead to acne and skin allergies, and may even lead to life-threatening chronic diseases, because they contain many cancer-related toxins.
Mclenna said that these cosmetics often have low quality and long storage period, and the content of preservatives such as parabens is higher than that of ordinary cosmetics.
She pointed out that Halloween cosmetics also contain phthalates, which can be detected in some people who need long-term makeup.
According to the website of Breast Disease Foundation, parabens are widely used for the preservation of beauty products. Phthalates exist in some plastics and beauty products, both of which are related to breast diseases, especially the latter will disturb the hormone secretion of human body, resulting in infertility and neonatal defects.
Mclenna also pointed out that dyes used in Halloween cosmetics, especially red and blue dyes, contain some substances that are easy to cause skin allergies and dermatitis.
However, McLennan suggested that iron fans still have some ways to reduce the harm of Halloween cosmetics, such as shortening the time of "makeup" on the skin as much as possible, not "makeup", completely removing makeup after the holiday, and never sleeping with makeup.
Scientific evidence that cosmetics are harmful to health 3 What are the hazards of long-term use of cosmetics?
It is a woman's nature to love beauty. As the saying goes, "three points of appearance, seven points of dress." It is not difficult to see that no matter how gorgeous a person is, perfect beauty can only be achieved through hard work. Perhaps it is "appearance first" or everyone loves "beauty", so I see that the number of beautiful women traveling on the street has increased geometrically. Whether it's beautiful and exquisite Japanese makeup or enchanting European and American styles, beautiful women seem to be more and more keen on piling cosmetics on their faces, trying to make themselves more beautiful ... I don't know that cosmetics are actually secretly hurting your innocent face, for the sake of beautiful makeup, you may eventually get hurt.
The harm of cosmetics is a serious topic for us who live in the material world every day. What is "cosmetic harm"? It refers to the chemical synthetic substances added to cosmetics and skin care products, which contain ingredients harmful to the normal and function of the skin and are harmful to the human body over time.
"If you wear makeup every day, you will absorb two kilograms of harmful substances a year." Recently, public health experts from the Health Supervision Bureau of the Health Department of Zhejiang Province made it clear that cosmetics should not be used in an uncontrolled way, especially in hot summer, when most capillaries in the whole body are open and blood circulation in the whole body is accelerated, which will increase the absorption of harmful chemicals.
Absorb two kilograms of harmful substances every year.
Miss Xu works in an office building. Every day before going out, she puts on some light makeup. First, she will use facial cleanser to clean her skin, and then use toner, lotion, moisturizing cream and sunscreen in turn. Then, she put a thin layer of sunscreen on her face. In order to make her face look better, she also used some liquid foundation, powder cake and loose powder. Finally, she painted her eyebrows and put on some lipstick before going out.
Many women will "do routine work" every day like Miss Xu before going out. However, public health experts from the Health Supervision Bureau of the Ministry of Health said that the abuse of cosmetics is harmful to health. If women use cosmetics every day, their bodies will absorb two kilograms of harmful chemicals within one year. Absorbing from skin and blood is more dangerous than eating directly.
According to the person in charge of the Cosmetics Department of the Health Supervision Bureau of the Health Department, cosmetics are not food after all, but must contain some chemicals that are potentially harmful to the human body in order to achieve the corresponding effect. Even some qualified products, the internal chemical composition content does not exceed the national allowable standards, but if used for a long time, it will also have an impact. What's more, there are still many fake and shoddy products and expired cosmetics, which are even more harmful.
No one can escape the fact of aging, but improper use of cosmetics and skin care products will undoubtedly accelerate the aging of the skin. Under the catalysis of advertising, the age of using cosmetics has dropped to 15 or 16, and more and more young people around the age of 20 have black spots. This shows that the harm of cosmetics can not be ignored.
Here are some examples of the most common dangers of cosmetics in daily life.
1, cosmetics can cause poisoning.
This group of products, which claims that pores can be invisible, has added salicylic acid. In fact, it is not a newly discovered magical ingredient. For a long time, it has been used as a topical medicine to eliminate warts, corns, tinea pedis, psoriasis and acne. The old medicine is newly used, and the salted fish turns over and returns to the table of cosmetics, becoming a skin care product with a high popularity index.
Salicylic acid, like fruit acid, achieves the so-called crystal clear effect by peeling off skin keratin.
1 July, 9881day, officially announced by the Health Department of Taiwan Province Province.
1September, 1988 to1June, 1989, the drug inspection bureau randomly selected 65 kinds of cosmetics in beauty salons and beauty materials stores, and found that 13 kinds of cosmetics contained salicylic acid, but they were sold as general cosmetics. Most of their advertising appeals are whitening and acne treatment, and many of them are illegally added.
2, cosmetics can cause allergies, fetal malformation.
From 65438 to 0988, it is claimed that acid can reduce wrinkles, improve skin color and promote skin tissue to delay aging. And so on, and it has been used as a prescription for treating acne, and it has gained several selling points overnight. Sales soared.
So far, experts are still not sure how acids act on the skin. But its function will stimulate the proliferation of epidermal cells, accelerate the metabolism of old cells and repair collagen. The function of expanding and thickening the epidermis to make wrinkles look inconspicuous does exist.
Acid A is used cautiously in Europe and is listed as a banned drug. 1In April, 987, the Health Department of Taiwan Province Province announced that it would be illegal to add A acid to cosmetics and skin care products.
It belongs to the medicine designated by the doctor, that is to say, it can't be used without a prescription. At present, the products sold by MLM can achieve the effect of removing spots and changing skin after use. Many people don't understand the reason, covet speed, and spend 20 thousand to 30 thousand to buy it A short-term effect, coupled with the neglect of follow-up maintenance, many people's black spots are more serious than before.
Some companies were promoted, and the Ministry of Health of Taiwan Province Province was punished in the name of selling medicines and cosmetics. It's not a heavy penalty, but also a high profit from pyramid schemes. It's right to change brands. Poor and poor victim, the injury is obvious on his face, but he has no recourse. It is not enough to say that he wants to cry.
The skin using acid will turn red, peel off, be sensitive, burn and even sting. Is a common reaction.
That's because A-acid is very sensitive to light, so it's not uncommon for people who don't do thorough sun protection to produce pigmentation and blackening. But long-term use of an acid will make the skin structure loose and fragile, which consumers must know.
According to the statement of American health officials on June 5438+1October 20, 2000, if women of childbearing age take acid A orally, it is suggested not to get pregnant for two years to avoid giving birth to deformed fetuses.
Although it is aimed at oral patients, we should not treat the permeability of skin for external use lightly, so as to avoid cosmetic failure and harm to the body.
3, there will be cosmetic dermatitis.
Cosmetic dermatitis refers to an inflammatory skin disease that causes the skin of face or other makeup parts when cosmetics are used in beauty or oil painting. The clinical manifestations are erythema, edema, blisters, papules, exudation, scabbing, itching, pigmentation and so on.
Generally speaking, there are two aspects. One is the inherent quality of cosmetic raw materials. Preservatives, decolorants, perfumes, sunscreens, sweating agents, emulsifiers, hair dyes and some heavy metal substances in cosmetics have different degrees of direct irritation to the skin or cause allergic reactions to the skin. Some ingredients in some cosmetics also have photosensitivity. After use, sunlight and ultraviolet radiation cause skin photosensitivity reaction, leading to erythema or pigmentation.
On the other hand, improper use of expired and contaminated cosmetics or methods, such as long-term use of pharmaceutical cosmetics containing steroid hormones, can cause folliculitis, hirsutism, vasodilation, skin atrophy and other reactions. Cosmetics may have direct primary irritation or allergic reaction after contacting the skin, and some photosensitive substances may have photosensitive reaction or phototoxic reaction after entering the skin, which is the basic pathology of cosmetic dermatitis.
The diagnosis of cosmetic dermatitis is not difficult, and there is a clear history of cosmetic contact; Good hair on the face and other makeup parts of the skin; Skin lesions are polymorphic, including erythema, edema, papules, papules, blisters, bullae, exudation, erosion, scabbing, hypertrophy, roughness, telangiectasia, skin atrophy and pigmentation. Of course, these manifestations do not necessarily appear at the same time. Although most people who use cosmetics are women, with the changes of the times, there are also many men who use cosmetics, which should be noted.
4. Anemia and alopecia
Dermatologists remind people that cosmetic preparations that remove pigments contain toxic chemicals such as inorganic mercury salts and hydroquinone, which are potentially harmful to human body after long-term use.
Usually the mercury in some soaps and whitening creams is mercuric chloride or mercuric iodide. Scientific research shows that both organic mercury and inorganic mercury are easily absorbed by normal skin. Therefore, if you apply whitening cosmetics 2-4 times a day, the chronic accumulation of mercury should not be underestimated. Medical research shows that the local toxicity of mercury can accumulate heavy metals in the skin, sometimes causing hyperpigmentation and contact dermatitis on the face and neck. In addition, the potential harm of mercury to the whole body can cause weight loss, burnout, anemia, hair loss, stomatitis and kidney damage? Proteinuria or something? Snow and central nervous system symptoms (such as headache).
5, endocrine disorders
Some young women like to use ointment such as Quyansong instead of beauty cosmetics. As a result, their temporary pituitary function, that is, adrenal function, is inhibited, which leads to endocrine disorder and brings pain to themselves. In order to make their breasts fuller and more attractive, some women use estrogen-added "breast cream" for a long time, resulting in irregular menstruation, pigmentation, dark spots, thinning and shrinking skin and other adverse reactions.
Therefore, do not use cosmetics containing hormones in beauty makeup to avoid the occurrence of "hormone beauty syndrome". When it is necessary to use beauty cosmetics containing certain hormone ingredients to treat diseases or other special circumstances, they should also be purchased and used under the guidance of a doctor. In the process of use, if there are allergic symptoms and phenomena such as itching, eczema, redness, abscess and ulcer, stop using it immediately.
6. "Lipstick disease"
The so-called "lipstick disease" is cosmetic allergy caused by lipstick on the lips. According to the survey, about 10% of women suffer from this disease because of lipstick. Lipstick is mainly composed of lanolin, wax, dye, essence and other ingredients. Lanolin is a natural animal fat, which contains cholesterol, lanosterol and glyceride, and can penetrate into the skin. Dyes, essences and other ingredients are complex, and these substances are easy to cause allergic reactions, leading to chapped lips, peeling and bloating inhibition, which affects the essential beauty of lips.
Wearing lipstick for a long time will also affect your overall health. Lanolin and wax in lipstick have strong adsorbability, which often adsorb dust, bacteria, viruses and some heavy metal ions in the air on the oral mucosa, which not only increases the probability of causing allergies, but also easily brings lipstick and harmful substances attached to it into the oral cavity when drinking water and eating, which is harmful to the body.
