Cold sore scabs form when blisters caused by the herpes simplex type 1 virus break and crust over. While sufferers may find the appearance of these scabs unsightly, they are an important stage in the healing process. For this reason, the scabs should not be disturbed, but be allowed to fall off of their own accord over the course of several days. Cold sore scabs cannot be prevented or cured once you have the herpes simplex type 1 virus. However, appropriate treatments may help relieve the discomfort felt during this stage of the virus, and encourage the skin's natural healing process.

Tips and warnings
- Avoid picking at or peeling off cold sore scabs to give the skin time to heal.
- Wash your hands before and after touching cold sore scabs to avoid passing on the virus or infecting other areas of your body.
- Consult your doctor if your cold sores do not heal in 10 to 14 days, if your symptoms are severe, if you frequently suffer from cold sores, if your immune system is compromised by an existing health condition such as cancer or HIV, or if you experience eye irritation.
- If you have a cold sore, or have recently had one, avoid close contact with those at increased risk of infection, such as infants, eczema suffers, or people with a suppressed immune system.
