COLD SORES
Cold sores develop on the face, most commonly on the outside of the mouth. They are caused by the virus Herpes Simplex and can be triggered by anything from infections to stress or even sunlight. They appear as itchy, tingling blisters. The area starts to weep and blister and is very painful. The blisters then crust over within a day or two. Most outbreaks last about 7-14 days. Once contracted, cold sores tend to be a recurrent condition.
TREATMENT
Aciclovir: Is the only antiviral product available over the counter and is the main go-to treatment for cold sores. It is available as a cream and may cause transient stinging after application to the cold sore. However this is only experienced in a minority of patients. It works best when applied at the tingly stage since it can actually stop the cold sore from forming. It should be applied sparingly five times a day.
Ammonia: is not an antiviral but may help to dry up lesions and prevent secondary infections. It can be used by all ages.
Urea: is of little use against the cold sore virus but is helpful in soothing and healing damaged lips.
Cetrimide and Chlorocresol are mild disinfectants that help control infection. Urea is a moisturiser that works by penetrating the surface of the lips, where it attracts and retains water. Urea also breaks down keratin in the skin cells, helping them to shed, which softens and improves the appearance of dry, cracked lips. Dimethicone acts as a water repellent to help protect the lips.
