Orgclinic.com advises treating cold sore scabs by applying a cloth dipped in ice-cold water to the affected area. To speed healing, Paula's Choice Skin Care recommends applying a thin layer of antibiotic ointment to the scab. Under no circumstances should the scab be picked at or removed as doing so can lead to even more cold sores. The scab must remain until it is ready to fall off.
Cold sores develop when delicate skin such as that found on the lips is attacked by the herpes virus. Sores progress through eight stages. Scabs appear at the end of the cold-sore cycle. During this time, it is normal for the skin to become dry and begin to peel around the lesion. A small amount of bleeding is also common, according to Orgclinic.com.
In addition to getting plenty of rest and exercise, What Allergy? recommends treating a cold sore with vitamin supplements such as zinc, as well as vitamins E and B. The site also advises keeping the area moist by applying lip balm or petroleum jelly.
Orgclinic.com states that a typical cold sore lasts approximately three weeks without treatment. Applying cold sore medications gets rid of most cold sores in less than a week.
