Several things can kill bacteria on skin, including:
- Rubbing alcohol: This is a common antiseptic that can kill bacteria like E. coli and Staphylococcus within 10 seconds. [Reference 1, Reference 2]
- Hydrogen peroxide: Another antiseptic that effectively kills viruses and various bacteria, though it might take longer than rubbing alcohol. [Reference 1, Reference 2]
- Antibiotic ointments: These can be used to treat minor skin infections and work by killing bacteria. [Reference 3]
- Medical-grade honey: This has been proven to kill antibiotic-resistant bacteria in laboratory settings. [Reference 4]
- Vinegar: This has antimicrobial properties and can kill bacteria and viruses, even treating yeast infections. [Reference 5]
It's important to note that while these substances can kill bacteria, they don't necessarily eliminate all bacteria on the skin. The skin has a natural microbiome, a diverse community of bacteria, fungi, and viruses, that plays an important role in skin health. [Reference 6] Some bacteria are beneficial and contribute to the skin's immune system and overall health. [Reference 7]
