0.1% incidence is greatly underestimated
Survey data: Before 2003, the number of outpatients in the dermatology department of the Air Force General Hospital was more than 100,000, and about 100 cases of cosmetic skin diseases were diagnosed. After 2004, the dermatology department of the hospital expanded, and the annual outpatient volume gradually increased to about 300,000. The medical history of cosmetic skin diseases has also increased to about 300 cases, and the incidence of cosmetic adverse reactions has always accounted for about 0.1% of outpatient dermatological patients.
Ordinary people may think that the 0.1% incidence is somewhat insignificant, but in the eyes of clinicians, this is already a serious figure. Even Liu Wei, deputy director of the dermatology department of the Air Force General Hospital, pointed out: "This number may have been greatly underestimated."
In 1992 and 1993, the Ministry of Health organized two cosmetic skin disease clinics in 10 major cities across the country, and treated 1493 cosmetic adverse reactions in a short period of one week.
In the daily consultation, a doctor in the dermatology clinic of a large hospital has to treat more than 60 patients every day, so there is not enough time for each patient with cosmetic adverse reactions to complete the national clinical examination, experiment, photography, record file and report, etc. A series of procedures. Some doctors worry about medical disputes or other after-effects, and treat patients with adverse cosmetic reactions as general contact dermatitis or other skin diseases.
Therefore, experts believe that the true incidence of cosmetic adverse reactions should be much higher than the above data.
Double the adverse reaction of imported cosmetics
Survey data: The clinical investigation and analysis of 1053 cases of cosmetic skin diseases in 2005 showed that there were 156 cases of skin diseases caused by imported anti-wrinkle cosmetics, and 82 cases of domestic products.
Although the consumption of imported and domestic cosmetics is not consistent, the skin problems caused by imported high-end cosmetics cannot be ignored.
If you want to change the cosmetics, you must first do a skin test before this. Apply it to the back of the ear or wrist and forearm. After 24 hours to 48 hours, there is no abnormality to use.
Cosmetic contact dermatitis up to 90%
Survey data: cosmetic adverse reactions include cosmetic contact dermatitis, cosmetic photodermatitis, cosmetic acne, cosmetic skin pigmentation abnormalities, cosmetic hair damage, and cosmetic nail damage. Among them, cosmetic contact dermatitis accounts for 70% to 90%; cosmetic acne incidence rate ranges from 3.5% to 10%; cosmetic skin pigment abnormality rate is about 10% to 50% of cosmetic adverse reactions.
We may have had a feeling of itching or stinging after using certain cosmetics. Cosmetic contact dermatitis includes irritant contact dermatitis and allergic contact dermatitis.
Among the adverse reactions caused by cosmetics, 90% are not allergic, just skin irritation, such as tingling and itching of the skin. As long as there are symptoms, you should change your brand immediately. Once you find a cosmetic that is safe to use and feels comfortable, don't change it easily. Because "often change cosmetics, the chance of allergies is even greater."
The most "poisonous" spice in cosmetics
Survey data: Common allergens, preservatives and hair dyes commonly found in cosmetics. Among them, spices are the most common ingredients causing allergies in cosmetics. When allergic reactions to cosmetics occur in patients with eczema, 30% to 45% are caused by cosmetic fragrances.
Spices are the soul of cosmetics and the most likely cause of adverse reactions. Due to the principle of confidentiality, the manufacturer will never disclose the fragrance used, so consumers cannot know whether they will be allergic to the fragrance used in the cosmetics before purchasing.
Formaldehyde, a preservative used in cosmetics, is a common sensitizer. Although few cosmetics use formaldehyde as a preservative, many other preservatives in cosmetics can also release formaldehyde after use.
There are four main causes of adverse reactions in cosmetics:
First, the quality of cosmetic hygiene is unqualified, such as the addition of prohibited substances or restricted substances exceeding the standard.
Second, consumers have allergies, improper cosmetics or improper use.
Third, labels and manuals exaggerate publicity and mislead consumers. In particular, there are more exaggerated publicity on the cosmetics sold in TV shopping and beauty salon services. For example, some advertisements for whitening and freckle products, the actors used to be as white and clean as a layer of skin, which obviously exaggerated the effect of cosmetics.
Fourth, beauty salons improperly apply cosmetics to consumers, and delays in treatment and improper handling are one of the important factors that cause the skin condition of cosmetic skin to worsen. Expert advice: Cosmetic allergy identification only 10 yuan due to cosmetics caused by allergies Want to return before the need to go to the Ministry of Health designated identification agencies for identification. At present, the Ministry of Health has set up appraisal points in 10 cities including Beijing, Shanghai and Guangzhou. The Air Force General Hospital is the only one in Beijing.
If the consumer suspects that his skin problem is caused by cosmetics, then bring suspicious cosmetics, first consult a doctor for a preliminary diagnosis of skin allergies, and then bring the product to the laboratory for patch testing. After two or three days, the results will be obtained.
