Cold Sore Treatment Singapore

Cold sores are caused by the herpes simplex virus type 1 (HSV-1), a highly prevalent virus that, once acquired, remains latent in the nervous system for life. Most people are exposed to HSV-1 in childhood. The virus periodically reactivates – particularly in response to physical or emotional stress – causing the characteristic cluster of blisters around the lips or mouth.

While cold sores are common and self-limiting in most cases, frequent recurrences or severe episodes benefit from specialist assessment and a structured management approach.

Signs & Symptoms

A prodromal phase of tingling, itching, or burning at the affected site, typically lasting several hours before blisters appear

Small clusters of fluid-filled blisters on or around the lips, under the nose, or on the chin

Blisters that rupture, crust over, and resolve over 7–10 days without scarring in uncomplicated cases

Pain or discomfort, particularly in the first day or two

In immunocompromised individuals, lesions may be more extensive, slower to heal, or atypical in appearance

Causes & Triggers

HSV-1 is transmitted through direct contact with an active lesion or with viral shedding from an infected individual, even in the absence of visible blisters. After primary infection, the virus becomes dormant and may reactivate when triggered by physical or psychological stress, febrile illness, intense sun exposure, hormonal changes, immunosuppression, or trauma to the perioral area.

Antiviral therapy – oral antivirals such as aciclovir or valaciclovir are most effective when started early, ideally during the prodromal phase. They shorten the duration and severity of episodes. Topical antivirals offer more modest benefit.

Suppressive therapy – patients with frequent recurrences (typically six or more per year) may benefit from daily suppressive antiviral therapy, which reduces the frequency of outbreaks and the risk of transmission.

Specialist assessment is advisable when cold sores are unusually frequent, severe, slow to resolve, or occurring in an immunocompromised individual.

Why Choose Specialist Surgical Care

Dermatological surgery performed by a specialist offers distinct advantages:

  • Accurate pre-surgical diagnosis with dermoscopy. Lesions are assessed carefully as appearances can be
    misleading without specialist evaluation
  • Appropriate margin assessment for cancer excisions based on lesion type and guidelines
  • Histological analysis of all removed tissue to confirm diagnosis and clear margins
  • Minimally invasive techniques selected to optimise cosmetic outcomes
  • Structured follow-up and surveillance for ongoing skin health
