The technical term for herpes on the face is herpes simplex virus type 1. This particular virus causes the outbreak of cold sores, fever blisters, and in some cases, bumps on the inside of the mouth. Currently, approximately 80% of the population suffers from HSV-1, and that number is steadily growing.
Everyone's facial herpes outbreaks are different. Generally, the first outbreak is more painful than the recurrences. Some people may suffer with swollen and red gums or painful sores on the inside of the mouth, while others just get a cold sore on the lip. Some carriers of the virus don't get blisters or sores at all.
