Cold sores are painful pus-filled blisters that typically appear on the face near the mouth. Cold sores are caused by a strain of the herpes virus and can recur throughout your lifetime. If you are unsuccessful at treating your facial cold sores at home, a doctor may recommend a topical pain relief ointment or an oral antiviral medication.
Hot and Cold Therapies
Although heat and cold won’t reduce the duration of a cold sore on the face, it can be used to alleviate pain associated with the skin condition. Apply a washcloth moistened with either hot or cold water. Place directly on the blister and leave in place for five-minute intervals throughout the day. After application, pat the area dry with a clean towel.
Petroleum Jelly
According to the Doctors Book of Home Remedies featured on the Mother Nature website, petroleum jelly can be applied to the blister to protect the area. Apply a generous amount of the petroleum jelly using a cotton swab. Avoid using your fingers because this can spread the infection.
Dietary Changes
The herpes virus requires argine, a type of amino acid to metabolize. Limit foods rich in argine to control outbreaks on the face from cold sores. Food items high in argine are nuts, legumes, chocolate, soft drinks, beer and grains. Adding more lysine, another type of amino acid, to your diet can control the number of outbreaks and severity of infection, according to the Doctors Book of Home Remedies. Aim for at least 2,000 to 3,000 mg daily of lysine if you suffer from cold sores. Food sources of lysine are milk, cheese, yogurt and potatoes.
Witch Hazel
Witch hazel or rubbing alcohol can be applied with the use of a cotton ball directly to the blisters on the face. The witch hazel can dry out the cold sore to alleviate discomfort and help heal the area quickly.
