What is Herpes Simplex?

A recurring blistering skin infection caused by HSV virus

Causes blisters around the lips (type 1) or genital area (type 2), with tingling followed by blisters that burst and crust.

Caution

Contagious during active blister phase; avoid direct contact.

Main causes & characteristics

Herpes simplex is an infection caused by the herpes simplex virus (HSV), divided into type 1, which mainly occurs around the lips, and type 2, which involves the genital area. After the initial infection, the virus lies dormant in nerve ganglia and reactivates when immunity drops or with fatigue, stress, or strong UV exposure; tingling or itching comes first, then clustered blisters form, burst, and crust over. It has the characteristic of spreading through contact.

How to manage

It is important to avoid touching or popping the blistered area and to wash your hands often to prevent spread to other areas or to other people. Reducing discomfort by moisturizing the lips and minimizing irritation, and managing your immune condition with enough sleep and rest, is generally recommended. If it recurs often or spreads around the eyes or over a wide area, consulting a dermatologist is recommended.

Good to know alongside

It differs from shingles (varicella-zoster virus) in the causative virus, and caution is needed when it spreads widely on atopic skin. It is highly contagious during the blister stage, so sharing towels and utensils should be avoided.

Everyday care tips

When you feel the prodromal tingling on the lips, try reducing irritation and resting early. Carrying a UV-protective lip product on days with strong UV can help.
