Cold sores on the lips can recur easily

If small blisters appear around the lips and are accompanied by tingling or itching, one possible cause among several is herpes simplex. Even though it may seem like a minor condition, recurrence is common, which can make it bothersome. Let’s take a look at how it is treated and managed.

Blisters on the lips?

Herpes simplex is one of the viral skin conditions many people experience, and when it occurs on the lips, it is also called cold sores. At first, it is easy to dismiss it as something mild, like a common cold, but because herpes simplex tends to recur, it is important to treat and manage it properly from the beginning. It is best not to touch it if possible and to see a doctor.

Herpes simplex is caused by a virus

Herpes simplex occurs due to herpes virus infection, and when it appears on the lips, it is usually caused by HSV-1. Once it enters the body, it remains latent in the nerve ganglia and has the characteristic of recurring when immunity drops, the body is tired, stress occurs, or there is excessive exposure to sunlight. The reason cold sores often appear when the season changes, during periods of overwork, or after having a cold is also related to this. The reason for frequent recurrence is that the virus remains in the body and becomes active again easily depending on environmental changes or a decline in physical condition.

How is cold sore treated?

In dermatology, characteristic blisters, red inflammation, and whether there is pain are checked, and if necessary, an accurate diagnosis can be made through viral differentiation tests or PCR tests. As for treatment, oral antiviral medication or topical agents may be considered to suppress viral multiplication and activity. If the pain is severe, supportive treatment to relieve symptoms may be used together. Although herpes simplex may improve naturally over time, starting medication early can shorten the duration of symptoms and help prevent complications, so treatment at the appropriate time is important.

Because herpes simplex can spread through direct contact, care should be taken not to touch the burst blister area and then contact another person’s face or body with the same hand. It can also spread through shared utensils, so extra attention to personal hygiene is needed when symptoms are present. This is especially important in households with children or family members with weakened immunity.

How can recurrence be prevented?

To prevent recurrence, managing immunity is above all important. It is good to get enough sleep, reduce stress, and avoid prolonged exposure to sunlight. Developing the habit of carefully applying sunscreen even around the lips can also help. For people whose cold sores recur frequently, it is also necessary to establish a long-term management plan through consultation with a specialist. Since cold sores are a viral condition, it is preferable to manage symptoms through an accurate diagnosis and systematic treatment rather than self-treatment or folk remedies.
