Herpes simplex is a viral disease of the skin and mucous membranes that causes painful blisters, most often on the lips. It is caused by the herpes simplex virus (HSV), which remains in the body for life after infection.

There are two main types of the virus: one most often affects the lips and face, the other the genital area. However, both types can appear on different parts of the body.

It is a very common condition. In most cases, herpes is mild and resolves within 1–2 weeks, but it can recur periodically. The disease is contagious, especially during active outbreaks.

What to do if you suspect it

If you notice burning, redness, or the appearance of blisters on the skin or mucous membranes, it is important not to ignore the symptoms.

First step — consult a doctor: a general practitioner or dermatologist.

Until medical evaluation, avoid touching or popping the blisters. This can increase viral spread and delay healing.

If outbreaks occur frequently, are very painful, or affect the eye area, seek medical care as early as possible.

Early consultation helps shorten the duration of outbreaks and reduce the risk of complications.

What the condition looks like

Herpes usually starts with tingling, burning, or itching on the skin. Within 1–2 days, small fluid-filled blisters appear in that area.

They form clusters on red and inflamed skin or mucous membranes. Over time, the blisters rupture, leaving small erosions that later crust over and heal.

Most commonly, lesions appear on the lips, around the mouth, and on the face. Other locations are also possible.

Main symptoms

Main manifestations are related to lesions and local discomfort.

Common signs include:

  • burning and tingling before lesions appear
  • painful blisters
  • itching and discomfort
  • redness and swelling of the skin

Swollen lymph nodes may also occur.

Causes

The cause is infection with the herpes simplex virus.

After initial infection, the virus remains dormant in nerve cells. Under certain conditions, it becomes active again and causes new outbreaks.

Transmission occurs:

  • through close skin-to-skin contact
  • through saliva (e.g., kissing)
  • through shared personal items

How it develops

After entering the body, the virus travels to nerve cells and remains there long-term.

When immune defense weakens, it reactivates and moves to the skin or mucous membranes, causing blisters.

After healing, it returns to a dormant state but may reactivate again.

Forms and types

Types of herpes differ mainly by location, but the disease mechanism is the same.

Frequency of outbreaks varies widely — from rare episodes to several times per year.

When to see a doctor

Seek medical attention if:

  • outbreaks occur frequently
  • pain or discomfort is severe
  • the eye area is affected
  • lesions are widespread or slow to heal
  • this is the first episode

People with weakened immune systems should also consult a doctor.

Treatment

Treatment aims to reduce symptoms and shorten the duration of outbreaks.

Antiviral medications are commonly used to suppress viral activity. They may be applied as creams or taken orally, depending on the situation.

Pain relief and skin care products may also be used to reduce irritation.

For frequent recurrences, preventive therapy may be recommended to reduce outbreak frequency.

It is important to understand that the virus cannot be completely removed from the body, but its activity can be controlled.

Q&A

Can herpes be completely cured?

No, the virus remains in the body, but its activity can be controlled and outbreaks reduced.

Is herpes contagious?

Yes, especially during active outbreaks, when close contact should be avoided.

Do you need treatment for herpes?

Treatment helps reduce symptoms and discomfort, especially in frequent or severe cases.

How long does herpes last?

Usually 7–14 days.

Can you pop the blisters?

No, this can spread the infection and delay healing.

Why does herpes come back?

It reactivates when the immune system is weakened.

Is herpes dangerous?

Usually not, but in some cases it requires medical supervision.

How to reduce recurrences?

Healthy lifestyle, skin protection, and following medical advice can help.
