Can human skin rust?

lol. long story but my friends and i were arguing over this and i have need of to know! does human skin rust (when wearing a metal ring)Can human skin rust?
By definition, rust is an oxidation of ferric materials, so humans can't rust. However, human skin is subject to oxidation, which weakens the cell and ages the skin. But you referred to wearing a metal ring. When wearing a metal ring, the moisture, salts and electrolytes produced by the skin may increase the rate of oxidation of doesn`t matter what metal the ring is made of, which will stain the skin. If it's an iron ring, it will rust. The oxidation of other metals may commonly be called tarnish. It sounds close to you and your friends have interesting conversations!
no, rust is a chemical aversion between the oxygen in nouns and ferric compound in iron...
however, our skin when we die also undergo a chemical reaction... decomposition which is triggered also by the oxygen contained by air and the carbon compound surrounded by our bodies...
If you've ever seen rust stains on your skin from wearing a see or ring next to your skin, what you're seeing is oxidation from the metal item transferred (by friction) to the skin. The oil on your skin and acidity of your sweat exacerbate the oxidation of most metals... speeding up the process, so to speak.
no
