What is Blistex Cold Sore Cream?

Blistex Cold Sore Cream is a topical treatment designed to treat cold sores caused by the herpes simplex virus. The active ingredient, Docosanol, helps to prevent the virus from entering healthy skin cells, which can reduce the duration and severity of cold sores when applied at the first sign of symptoms.

How the cream works

Docosanol, the active ingredient in Blistex Cold Sore Cream, works by altering the structure of the virus's outer membrane, preventing it from fusing with the host cell membrane. This action inhibits the virus's ability to replicate and spread, thereby reducing the duration of the outbreak and helping to alleviate symptoms such as itching, pain, and burning.

Using Blistex Cold Sore Cream is simple:

  1. Wash your hands thoroughly before applying the cream.
  2. Apply a small amount of cream to the affected area at the first sign of a cold sore (such as tingling, redness, or itching).
  3. Rub the cream gently into the skin until it disappears.
  4. Repeat application 5 times a day until the cold sore heals.
  5. Avoid touching the cold sore to prevent spreading the virus.
