I just bought some cheap earrings from this beauty supply store but they said surgical steel So will they prevent my ears from bleeding / infection ?
Surgical steel is a grade of steel often used in medical appliances like tweezers, forceps, etc. It's generally non-reactive and considered very safe. It doesn't contain any special properties against infection--you still have to observe basic hygiene and clean your piercings properly--but most people can wear surgical steel earrings without a problem. However, if you have a contact allergy to base metals like nickel, surgical steel may cause redness or irritation because of the metals used in it. If cheap rings or necklaces make your skin break out in a rash you should NOT wear surgical steel.
