Will a cold sore get infected if someone puts make up on it?

Applying makeup to a cold sore can increase the risk of infection and prolong healing time.

* Makeup contains bacteria. When you apply makeup to a cold sore, you can transfer bacteria from the applicator or brush to the sore. This can lead to infection.

* Makeup can block air flow. Cold sores need air to heal. When you apply makeup to a cold sore, you can create a barrier that blocks air flow and prevents the sore from healing.

* Makeup can irritate the skin. Cold sores are already irritated and painful. Applying makeup to a cold sore can further irritate the skin and make it more painful.

If you have a cold sore, it's best to avoid applying makeup to it. You can help speed up the healing process by keeping the sore clean and dry, applying a cold compress, and taking over-the-counter pain medication.
