Cold sore outbreaks may be influenced by stress, menstruation, sunlight, sunburn, fever, dehydration, or local skin trauma. Surgical procedures such as dental or neural surgery, lip tattooing, or dermabrasion are also common triggers.
Cold sores are caused by the herpes simplex virus (HSV). Most cold sores are caused by the type 1 strain (HSV-1). The type 2 HSV strain (HSV-2) usually causes genital herpes but very occasionally can cause cold sores around the mouth. See separate leaflet called Genital Herpes for more details. A first cold sore usually occurs in childhood.
