Is surgical stainless steel safe for metal allergies?

Surgical stainless steel has attracted attention as a material that is less likely to cause metal allergies, but in reality, it depends on the individual. However, it is less likely to cause allergic reactions than inexpensive accessory materials such as brass, chrome or gold plating, and is said to be safer than precious metal materials such as silver 1425 or pink gold, which contain a lot of copper, or ordinary stainless steel. Metal allergy occurs when sweat or saliva comes in contact with metal and reacts to metal ions or nickel contained in the metal. In the case of surgical stainless steel, the [passive film] covering the surface makes it difficult for metal ions to leach out, so it is said that metal allergies are less likely to occur.

Can I take a bath with surgical stainless steel jewelry?

Surgical stainless steel is a material that is relatively resistant to rust, corrosion, and heat, so there is basically no problem even if you bring it into the bath. In case of taking a bath in a hot spring, it is recommended to remove it before taking a bath because it may rust depending on the ingredients.
Also, contact with bath salts or body soap may cause deterioration, so be sure to rinse them off thoroughly and then wipe them dry with a soft cloth to prevent scratching.
