Use 9% hydrogen peroxide to clear your cold sore. Hydrogen Peroxide (H202) in very simple terms is water (H20) with an extra oxygen (0) molecule attached to it. When Hydrogen Peroxide is exposed to your skin it breaks down into water and oxygen. The extra oxygen molecule that is released is a highly reactive free radical which will help to clear the cold sore virus. It is able to do this because most of the good bacteria in the body survive in the presence of oxygen and most strains of viruses and bacteria cannot survive in the presence of oxygen.

What You'll Need

  • 9% Hydrogen Peroxide
  • Water
  • Cue tip

What You'll Do

  • 1. Dilute the 9% hydrogen peroxide with water (follow the instruction on the bottle as to how much water is required).
  • 2. Apply the solution to the cold sore using a cue tip
  • 3. Re- apply the solution every few hours (at least 4 times a day).

Tips & Warnings

  • You can purchase 9% hydrogen peroxide from most pharmacies. The hydrogen peroxide solution will bubble as you apply to the cold sore and may cause a tingling or slight burning sensation. Hydrogen Peroxide is most effective when you feel a cold sore starting to develop, in the tingling stages. Most cold sore attacks occur when a person is run down so it is important to boost your immune system and drink plenty of water while treating the cold sore.
