Herpes labialis is a lesion on the skin of the lips caused by the infection of a virus, the Herpes Simplex HSV-1 virus.
It is characterised by the appearance of small blisters filled with fluid that are usually grouped in circles on or around the lips. Once they are cured, they dry, although sometimes they become infected and ulcerate. These lesions heal spontaneously in several days, but they can last 3 to 4 weeks. They are normally recurrent lesions.
Why do herpes labialis appear?

Once the infection is suffered, the virus lies dormant in nerve cells of the skin and trigger for any reason and may reappear in the same place. As precipitating causes:
- Fever.
- Viral infections.
- Stress and fatigue.
- Solar and wind exposure.
- Hormonal changes.
- Alterations in the immune system.
