Causes of Metal Allergy and the Measure

What is Metal Allergy？

Metal from accessories and daily necessities can lead to metal allergy、It is said to be a phenomenon (allergenic contact dermatitis) that causes dissolution reaction when the same metal touches, when it dissolves while sweat or body fluid etc. slightly and ionized metal enters the body.

The easiest happen thing is when you wear earrings for the first time. The ring is encrusted by the thick skin of the finger and metal is difficult to enter the body, but the earrings cause a rejection reaction because the metal directly contacts the subcutaneous tissue through the skin.

Can not treat metal allergy?

There is sensitization that bodies are recognized by the body and stored to prevent the next invasion.。Once sensitized, metal allergy lasts for as long as it can be.
It works to refuse entry to substances that should not be present in the body and to cause an immune response. When it is sensitized there, it inflames every contact with a very small amount of the causative agent (metal that causes allergy).

What cause metal allergy?

Metal allergy is not affect to anyone, it changes depend on the kind of metal and the person wearing。The less expensive metals such as nickel and cobalt are easier to cause metal allergy。
It also depends on the frequency and the person who wears the metal。The first contact may cause sensitization, but it may be sensitized, for example, over several decades, after repeated contacts.。Also, if you wear it in summer, which often sweats, the sweat will melt the metal slightly, making it easier to happen.
Various factors are combined with other constitutions of the person who wears, for example, people who are easy to sweat, people who are hard to scratch, people with thick or thin skin, and allergies are caused。

What kind of metal that causes allergy?

Many of the metal products used in household products are coated with various metal surfaces in the form of plating in order to improve color tone and to provide corrosion resistance.
Many of the metals used in accessories use or are plated on alloys。It can be said that any metal has the potential to cause allergies.
The leading cause of allergic contact dermatitis is nickel. Chloride ion in the sweat has a strong effect of dissolving nickel, and people with nickel allergy in the past may develop dermatitis with just a small amount of sweat wearing a nickel product.
Metals prone to metal allergies are:
①Following nickel
②Cobalt / Chrome
③Zinc / Manganese / Copper
④Silver / Platinum / Palladium / Gold
⑤Being titanium.
Titanium is a skin-friendly material also used for medical transplantation。It is an allergy free material that can be worn even by sensitive skin that has been hampered by gold and platinum.

Allergy Test？

Contact allergy such as metal allergy is examined by Patch Test。In the test, a sticker with a test drug is put on the back and arms to test the reaction。Testing agents include gold, silver, nickel, chromium and cobalt.
And because expenses can be applied to insurance, people with a 30% burden will be examined for around 700 yen, so it would be better if they could take a test once.

How do we can prevent metal allergy？

People who have allergies they not often wear metal.
If a doctor performs a patch test (a plaster with a solution of metal such as gold, silver, platinum, etc. is applied to the skin), which metal is covered by the doctor, it can be prevented by not using the covered metal.

Keep your earrings clean！

It is important to keep the first earrings clean as it is a raw wound condition。However, it seems that there are many cases where it is rash by over-disinfection (especially strong antiseptic solution such as alcohol) because it is mistaken for sanitization and disinfection, and it is further exacerbated.

Be careful about material selection

Gold, silver and platinum are metals that are unlikely to cause metal allergies。By using high quality products that do not use alloys such as nickel, you will be less likely to cause allergy。
In addition, if you put something short in the length of the earrings post, it squeezes the earlobe and it is easy to cause allergy.
According to a survey by the Ministry of Health, Labor and Welfare, allergic contact dermatitis is the most common skin trouble caused by accessories, and about 80% of the cause is said to be metal.。However, silver is not toxic and it is very safe . That is why silver is used in dishes and dental dentures.
It can be said that highly pure silver is very unlikely to cause allergies.

If you really want to put on metal allergy, Glass coating will help you!

As a feature of the glass coating, the surface of the product is different from the original component because the application forms an inorganic glass film on the surface.。
For this reason, it is a tool that is very beneficial for people with metal, silver and allergies.。
The reaction of silicon compounds and dibutyl ether, which are the main components of the solvent, with moisture forms a colorless and transparent glass film with a thickness of 300 to 800 nm per layer as shown in the image below. (In GLATION, it is constructed three times.)

As a female customer, rings, necklaces, earrings and bracelets. If you are a male customer, watch buckles and sunglasses, you can apply a glass coating to a variety of items
(Caution: There are individual differences in the way of effect.)
