1, the harm of common cosmetics
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 checked the content of salicylic acid in 65 kinds of cosmetics in beauty salons and beauty materials stores. It was found that salicylic acid was contained in 13 product, but it was sold in generalized form. 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 are soaring.
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 acid A to chemicals 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.
Once a company was promoted, the Ministry of Health of Taiwan Province Province was punished in the name of selling drugs. 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 cried without tears.
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.
