Why does wearing alloy jewelry attract dermatitis?

Wearing alloy jewelry leads to dermatitis, and many people choose to buy alloy jewelry for various reasons. Wear it in hot summer, and their skin will become inflamed. Next, I will show you why wearing alloy jewelry can cause dermatitis.

Why does wearing alloy jewelry cause dermatitis? Not long ago, when traveling abroad, Xiao Qi bought some beautiful and cheap alloy jewelry. After wearing it for a few days, his neck and wrist broke out in a rash and he felt uncomfortable all over. She hurried to the hospital, and the doctor diagnosed it as "jewelry dermatitis".

Gao Yanqing, chief physician of dermatology department of Beijing You 'an Hospital affiliated to Capital Medical University, told the reporter of Life Times that chromium and nickel metals in alloy ornaments are the most common allergens of contact dermatitis in recent years, and the sensitivity of women to chromium and nickel is about 10 times that of men. In dermatitis caused by wearing jewelry by dermatosis patients in China, common jewelry, such as rings, earrings, necklaces, bracelets, watches, glasses frames, underwear buttons, scarves containing metal wires, etc. Both contain chromium and nickel, and direct contact will cause skin inflammation. Mainly manifested as itching and burning sensation, but also erythema, papules, erosion and so on. In severe cases, it will also form ulcers and induce systemic diseases such as asthma or urticaria.

In addition, unqualified jewelry may also contain radioactive elements, causing radioactive pollution. For example, some unqualified gold ornaments will not only cause allergies, but also cause radiation damage to the skin. This is because some radioactive elements, such as cobalt, radium, polonium and gold, will remain in jewelry during mining, smelting and processing, causing radioactive pollution. Therefore, we should also pay attention to the quality of gold jewelry when buying.

Gao Yanqing suggested that when buying jewelry, choose less alloy jewelry plated with nickel, silver and chromium. People or children with allergic constitution, especially scar constitution, should not bring metal jewelry.

In addition, if you sweat more in summer, you should wear less jewelry. Don't wear the ring too tightly and don't wrap it in wool. Try to avoid wearing jewelry all day and get into the habit of taking it off at night. Don't wear jewelry at night. First, let your skin rest. Second, reduce the harm of radioactive sources to human body by half. Some people are too lazy to take off earrings and other accessories when they sleep, which will inevitably hurt the skin behind their ears; Some people like to wear watches when they sleep, which is not conducive to the blood circulation of their arms. On the other hand, if the watch is luminous, the radioactivity of fluorescence will also cause harm to the body.

Why does wearing alloy jewelry attract dermatitis? Summer is the high incidence of jewelry dermatitis.

In summer, many girls have more exposed parts, and more girls choose different jewelry to wear. Therefore, contact dermatitis caused by metal jewelry, also known as "jewelry disease", has also increased a lot.

This is because people come into contact with some metals contained in jewelry, such as nickel and chromium, which will cause allergic reactions. Chromium and nickel in jewelry are the most common allergens of contact dermatitis in recent years, and the sensitivity of women to chromium and nickel is about 10 times that of men. Dermatitis caused by wearing jewelry accounts for nearly 10% of patients with dermatoses. Common jewelry, such as rings, earrings, necklaces, bracelets, watches, glasses frames, underwear buttons, scarves containing metal wires, etc. Both contain chromium and nickel, and direct contact with the skin can cause inflammation. Mainly manifested as itching and burning sensation, but also erythema, papules, erosion and so on. In severe cases, it will also form ulcers and induce systemic diseases such as asthma or urticaria.

Some people's allergic symptoms are only manifested in the parts where jewelry touches the skin, such as ears, neck, wrists, fingers, etc. Some people also have systemic allergic reactions. First, the skin will be red and swollen, and then it will start to get pimples and blisters, and the whole body will itch and feel uncomfortable. In general, patients with allergic reactions caused by jewelry can be cured by using some topical drugs to treat skin diseases. However, if the skin is repeatedly stimulated by inflammation, it is prone to malignant lesions and may cause cancer.

However, not all jewelry will cause allergic reactions in susceptible people. Pure gold, pure silver or high-grade jewelry and jade jewelry usually cause less allergies, while some low-grade simulated decorative jewelry or chemically treated jade jewelry are easy to cause allergic reactions.

Causes of dermatitis

1. The primary stimulation of these substances has no individual selectivity, and can occur after anyone touches them, without incubation period, and directly damages the skin through non-immune mechanisms. When the irritant is removed, the inflammatory reaction can disappear quickly. Such as strong acid and alkali, anyone exposed to a certain concentration for a certain period of time will have acute dermatitis at the contact site. The other is long-term exposure to substances with weak stimulation, such as soap, washing powder, gasoline and engine oil, which are mostly caused by long-term repeated contact. This is related to the nature and physical state of the primary irritant, individual factors such as skin hyperhidrosis, sebum, age, gender, genetic background and environmental factors.

2. Allergic reaction is mainly type ⅳ allergic reaction, which is a cell-mediated delayed allergic reaction. You won't get sick immediately after the first contact with allergens. After an incubation period of 4-20 days (average 7-8 days), the body became sensitized at first, and dermatitis appeared about12-48h after the second contact with allergens.

3. Skin lesions are generally confined to contact parts, mostly exposed parts. The boundary is clear and the shape is roughly consistent with the contact object. But it may also be because of scratching or other reasons that other parts of the body contact, or even because the body is in a highly sensitive state and spread to the whole body. Consciously burning itching and severe pain, a few patients, especially those with systemic rash, can sometimes cause systemic reactions, such as chills, fever, nausea and headache.

What should I do if I get jewelry dermatitis?

1, first remove the jewelry and remove the cause;

2, the rash is mild, and it can be cured only by treating skin diseases with some topical drugs;

3. For patients with severe rash, wet compress with 3% boric acid solution, external application of calamine lotion or solid such as Fuxiliao and Ailesong should be selected as appropriate.

Corticosteroid cream can be used externally, and antihistamines such as cetirizine hydrochloride, cimetidine and propranolol can be taken according to the doctor's advice;

4. It is particularly important to note that if the rash spreads to the face, please choose non-steroidal anti-inflammatory drugs (that is, non-hormonal drugs such as Bute and compound camphor ointment) for external use to avoid side effects such as pigmentation, decline or shedding.

How to prevent jewelry dermatitis?

1, try not to choose alloy jewelry plated with nickel and chromium when buying jewelry.

2. People with allergies should not wear metal ornaments. Sweat more in summer, so wear less jewelry.

3. Don't wear the ring too tightly, and don't wrap the ring with wool.

4. Get into the habit of picking jewelry at night. Not wearing jewelry at night can not only rest the skin, but also reduce the harm of radioactive sources to the human body. Take off earrings and other accessories before going to bed to prevent the skin behind the ear from being pricked.

5, before going to bed, you should take off your watch and sleep with it, which is not conducive to the blood circulation of your arm. In addition, if the watch is luminous, the radioactivity of fluorescence will also cause harm to the body.

Prevention methods of daily dermatitis:

1, increase outdoor activities, first receive a small dose of ultraviolet radiation, and gradually increase the amount of light, in order to gradually improve the body's tolerance to light irradiation, beware of sudden and long-term intense sunlight irradiation. If you travel, you'd better wear a wide-brimmed protective hat, or cover it with a sunshade and wear light-colored long-sleeved clothes.

2. Do not use cosmetics containing more photosensitive substances, such as impure vaseline and inferior aromatic skin care products.

3. Try to eat less or not to eat light-sensitive foods that are easy to cause spring dermatitis, such as snails, amaranth, shepherd's purse, lettuce, purslane, rape, spinach, wild oats, Malantou, figs, radish tassels, etc., which contain more light-sensitive substances, which can improve the skin's sensitivity to ultraviolet rays and should be eaten less.

4. Apply sunscreen and other protective agents to protect the skin. Be careful of dermatitis when traveling!

5. It is best for women with sensitive skin not to change new cosmetics and skin care products in spring, nor to dye their hair or perm.

6. Wash your face with water after you go home. Pay attention to wash your face with cold water instead of alkaline soap. Pay attention to moisturizing. People with sensitive skin can use hospital preparations, such as silicone cream and vitamin E milk, to protect their skin.
