Should I put hydrogen peroxide on wounds? What to know.

When treating minor cuts and scrapes at home, many of us reach for that familiar brown bottle: hydrogen peroxide. It's been a staple in medicine cabinets for generations, fizzing on contact with a wound in a way that seems to signal its germ-fighting powers.

But is it really the best choice for wound care? In this article, we'll demystify hydrogen peroxide and explore the best ways to care for your minor wounds.

How hydrogen peroxide works.

Hydrogen peroxide is a chemical known for its antiseptic properties.

When you pour it on a wound, it releases oxygen bubbles. This fizzing action is more than just a visual effect; it helps to clean the wound by loosening debris and dead tissue from the affected area.

However, it's not all about the bubbles.

Hydrogen peroxide's effectiveness as a disinfectant comes from its ability to release oxygen. This oxygen-rich environment is hostile to anaerobic bacteria, which don't like oxygen and often cause infections in wounds.



Should I use hydrogen peroxide on wounds?

Hydrogen peroxide was a go-to remedy for cleaning cuts and scrapes for many years. However, while it kills bacteria, it might also harm the cells essential for wound healing.

Our skin and tissues have cells called fibroblasts, which play a crucial role in healing. When applied to a wound, hydrogen peroxide can harm these fibroblasts and the bacteria. This means that while you're killing germs, you might also be slowing down your body's natural healing process.

Considering this, many healthcare professionals now recommend using hydrogen peroxide with caution, especially for deep or serious wounds.



What can I use to disinfect a wound?

So, if hydrogen peroxide might not be the best choice, what should you use to clean a wound? Here are some gentler but effective alternatives:

  • Clean water. Often, the simplest solution is the best. Rinsing a wound with clean, running water is an excellent way to reduce the risk of infection and remove debris.
  • Mild soap. You can use mild soap and water for extra cleaning power. Be gentle and avoid getting soap directly in the wound, which can irritate it.
  • Saline solution. A saline solution, essentially sterile saltwater, can be an excellent choice for cleaning wounds. It's gentle on the skin and mimics your body's natural fluids, making it less likely to cause irritation.
  • Antibiotic ointments. After cleaning the wound, applying an antibiotic ointment can help prevent infection. These ointments create a protective barrier over the wound, often containing ingredients that kill bacteria.




While hydrogen peroxide has been a long-standing household remedy for cleaning wounds, weighing its benefits against the potential drawbacks is essential.

For minor wounds, simple cleaning methods like water and mild soap are often enough. Remember, it's always best to seek professional medical advice if you have a serious cut, a puncture wound, or any concerns about an injury.
