Regular use of cosmetics is harmful to the body. British biochemist Richard Burns warned that women who wear makeup every day to enhance their beautiful appearance also inhale an average of about 2.3 kilograms of chemicals into their bodies every year.

When women use cosmetics, chemicals enter the body through the skin and are absorbed by the body. In comparison, direct consumption of these chemicals may cause less harm to the human body.

If lipstick enters the mouth, its chemical components will be broken down by enzymes in saliva and gastric juice. But if applied to the mouth, the chemicals will enter the bloodstream directly.

The emergence of certain cancers may be related to people’s heavy use of certain types of cosmetics. At the same time, some cosmetics may also cause irritation to the skin and even accelerate aging.

“If you wear makeup every day, you will absorb two kilograms of harmful substances in a year.” Recently, public health experts from the Health Supervision Bureau of the Zhejiang Provincial Department of Health made it clear that you should not use cosmetics without restraint, especially In the hot summer, most of the capillaries in the body are open, blood circulation throughout the body is accelerated, and the absorption of harmful chemicals is increased.

Absorb two kilograms of harmful substances every year

Ms. Xu works in an office building. Before going out every day, she puts on some light makeup. She cleanses her skin with facial cleanser first, and then uses toner and makeup in sequence. Water, moisturizing cream, isolation cream skin care. Then, she applied a thin layer of sunscreen on her face to make her face look better. She also used a little liquid foundation, pressed powder and loose powder. Finally, she drew her eyebrows and put on some lipstick before going out.

Many women do a daily "routine" like Miss Xu before going out. However, public health experts from the Health Supervision Bureau of the Department of Health said that the abuse of cosmetics is harmful to the body. If a woman uses cosmetics every day, her body will absorb two kilograms of harmful chemicals in a year. Absorption from the skin and blood is more dangerous than direct consumption.

The chief of the Cosmetics Section of the Health Supervision Bureau of the Department of Health said that cosmetics are not food after all. To achieve the corresponding effects, they must contain some chemicals that are potentially harmful to the human body. Even in some qualified products, the chemical content inside does not exceed the national allowed standards, but if used for a long time, it will have an impact. What's more, there are also many fake and inferior products and expired cosmetics, which is even more harmful.

No one is immune to the fact of aging, but improper use of cosmetics and skin care products will undoubtedly accelerate the aging of the skin.

Catalyzed by advertising, the age of use of cosmetics has dropped to fifteen or sixteen years old, and there is also an increasing trend of young people who develop dark spots around the age of twenty. It can be seen that the harm of cosmetics cannot be ignored.

The following are examples of some of the most common hazards of cosmetics in daily life.

1. Cosmetics can cause poisoning

This group of products that claim to make pores invisible contains the ingredient salicylic acid. In fact, it is not a newly discovered magical ingredient. It has long been used as a topical medicine to remove warts, corns, tinea pedis, psoriasis, and acne. Old medicines repurposed, salted fish made a comeback and returned to the cosmetics market. It has become a highly popular skin care product that is selling like hot cakes.

Salicylic acid, like fruit acids, achieves the so-called crystal clear effect by exfoliating the skin.

Starting from July 1, 1988, Taiwan’s Department of Health officially announced that from September 1988 to January 1989, the Drug Inspection Bureau A random inspection of the salicylic acid content of 65 cosmetics found that 13 contained salicylic acid, but were sold as ordinary cosmetics. Most of the advertising claims were for whitening and treating acne, and many of them were illegally added in excessive amounts.

2. Cosmetics can cause allergies and fetal malformations

In 1988, a study claimed that A acid can reduce wrinkles, improve skin tone, enhance skin tissue and delay aging. It has many other effects, and it has always been used as a prescription for acne treatment. It has gained several selling points overnight. Sales surged.

So far, experts are still not sure how A acid works on the skin. But its effect 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 less obvious does exist.

The use of A acid is cautious in Europe and is listed as a prohibited drug. Taiwan’s Department of Health announced in April 1987 that A acid must not be added to cosmetics and skin care products, otherwise All are illegal.

It is a medicine designated by a physician, which means that it cannot be used without authorization unless prescribed by a doctor. Currently, the products are sold through pyramid schemes. The industry emphasizes that after use, it can achieve the effects of removing spots and resurfacing. Many people don't know the reason and just want to be quick and buy them at a high price of 20,000 to 30,000 yuan. After the short-term effect, many people develop dark spots that are more serious than before due to neglect of follow-up maintenance.

In the past, some businesses were reported to the Taiwan Ministry of Health and were punished for selling drugs and cosmetics. With light penalties and the high profits of MLM, you can still sell it under another brand name. The poor and pathetic victim, whose injuries were clearly visible on his face, had no way to ask for compensation. To say he was crying without tears was an understatement.

The skin using A acid will become red, peeling, sensitive, burning, and even stinging. is a common reaction.

That’s because A acid is extremely sensitive to light, so it’s not uncommon for people who don’t do a good job of sun protection to develop dark pigmentation. However, long-term use of A acid will cause the skin structure to become loose and fragile, which consumers must be aware of.

According to U.S. health officials on January 20, 2000, women of childbearing age are advised not to become pregnant within two years if they take oral acid A to avoid giving birth to a fetus with malformation.

Although it is recommended for patients who take it orally, we cannot take it lightly regarding the permeability of external use on the skin, so as not to cause damage to the body instead of beauty treatment.

3. Cosmetic dermatitis will occur

Cosmetic dermatitis refers to an inflammatory skin disease caused by the use of cosmetics or oil paint on the skin of the face or other makeup parts. The clinical characteristics include erythema, edema, blisters, papules, exudation, scabs, itching, and pigmentation on the face and makeup areas.

To sum up, there are roughly two aspects: one is the inherent quality problem of cosmetic raw materials, preservatives, decolorants, spices, sunscreens, antiperspirants, emulsifiers, hair dyes and some heavy metal substances in cosmetics , all directly irritate the skin or cause skin allergic reactions to varying degrees; some ingredients in some cosmetics are also photosensitive. After use, exposure to sunlight and ultraviolet rays can cause skin photosensitivity, resulting in skin erythema or pigmentation.

On the other hand, using expired, spoiled, contaminated cosmetics, or using them in inappropriate ways - such as long-term use of medicinal cosmetics containing steroid hormones, etc., can cause folliculitis, hirsutism, vasodilation, and skin irritation. Atrophy and other reactions. When cosmetics come into contact with the skin, they may cause direct primary irritation or hypersensitivity reactions. Some photosensitive substances may cause photosensitivity reactions or phototoxic reactions after entering the skin. These are the basic pathologies of cosmetic dermatitis.

The diagnosis of cosmetic dermatitis is not difficult as long as there is a clear history of contact with cosmetics; it often occurs on the skin of makeup parts such as the face; the skin lesions are polymorphic, with erythema, edema, papules, papulo-herpes, blisters, etc. Bullae, exudation, erosion, scabs, hypertrophy, roughness, telangiectasia, skin atrophy, pigmentation, etc. Of course, these manifestations do not necessarily occur at the same time. Although most of the people who use cosmetics are women, with the changes of the times, there are also many men who use cosmetics. This should be paid attention to.

4. Anemia and hair loss

Dermatologists warn people that pigment-removing cosmetic preparations contain toxic chemicals such as inorganic mercury salts and hydroquinone, and long-term use is potentially harmful to the human body. .

The mercury commonly found in some soaps and skin whitening creams is mercury chloride or mercury iodide. Scientific research shows that both organic and inorganic mercury are easily absorbed by normal skin. Therefore, if whitening cosmetics are applied 2-4 times a day, the chronic accumulation of mercury cannot be underestimated. Medical research shows that mercury’s local toxic effects can cause heavy metals to accumulate in the skin, sometimes causing hyperpigmentation and contact dermatitis on the face and neck. In addition, mercury has potential harm to the whole body, including weight loss, fatigue, anemia, hair loss, stomatitis, kidney damage, proteinuria, and central nervous system symptoms (such as headaches).

5. Endocrine disorders

Some young women like to use ointments such as Quyan pine instead of cosmetics. As a result, their pituitary gland or adrenal gland function is temporarily suppressed, causing endocrine disorders. Inflict pain on yourself. In order to make their breasts fuller and more attractive, some women use estrogen-added "breast enlargement cream" for a long time, which results in adverse reactions such as irregular menstruation, pigmentation, dark spots, skin thinning and atrophy.

Therefore, cosmetics containing hormones should not be used for beauty and makeup to avoid the occurrence of "hormone beauty cosmetics syndrome". When cosmetics containing certain hormone ingredients must be used to treat diseases or other special conditions, they should also be purchased and used under the guidance of a doctor. During use, if allergic symptoms and phenomena such as itching, eczema, redness, abscesses, and ulcers occur, you should stop using it immediately.

6. "Lipstick disease"

The so-called "lipstick disease" is a cosmetic allergy caused by applying lipstick on the lips. According to surveys, about 10% of women suffer from lipstick. I have suffered from this disease due to wearing lipstick. Lipstick is mainly composed of lanolin, wax, dyes, flavors and other ingredients. Lanolin is a natural animal fat containing cholesterol, lanosterol and glycerol that can penetrate the skin. Ingredients such as dyes and fragrances are even more complicated. These substances can easily cause allergic reactions, lead to dry lips, peeling lip skin, suppress swelling, and affect the essential beauty of lips.

Wearing lipstick for a long time will also affect your overall health. The lanolin and wax in lipstick have strong adsorption properties and often adsorb suspended matter such as dust, bacteria, viruses and some heavy metal ions in the air to the lip mucosa. This not only increases the chance of allergies, but also increases the risk of allergic reactions. When drinking or eating, it is easy to bring lipstick and harmful substances attached to it into your mouth, which is harmful to your health.
