About metal allergies
How do metal allergies occur?
When you wear earrings, your earlobes get itchy, when you wear a necklace, your neck gets red and swollen... Such skin rash caused by metals is called "allergic contact dermatitis." What causes such allergic reactions?
The cause of metal allergies is not the metal itself, but a substance called an allergen, which is made up of proteins in the body.
Like hay fever, an allergic reaction occurs when the body recognizes a substance as foreign and tries to prevent its entry, a process called "sensitization."
Titanium, a metal that is less likely to cause allergies
We come into contact with many metal products in our daily lives. Household items and accessories can also cause allergies. However, even under the word "metal," there are many different types, and some are more likely to cause allergies than others. Titanium is one of the metals that is less likely to cause allergies.
titanium
The surface is covered with an oxide film, which makes it difficult for the metal ions inside to dissolve, making it less harmful to the human body.
Surgical Stainless Steel
It is an alloy that contains metals such as chromium and nickel that are likely to cause metal allergies. Stainless steel is also magnetic.
金
Skin contact is unlikely to cause an allergic reaction, but contact with subcutaneous tissue of the human body, such as through piercings, may cause a reaction.
nickel
Metals are the most common cause of allergic contact dermatitis. Even if the surface has been treated, metal allergies can occur due to wear and tear.
