Lip herpes basics
Lip herpes, medically known as herpes simplex virus type 1 infection, commonly presents as grouped vesicles around the lips and perioral region. A prodrome of tingling, itching, or warmth often precedes the outbreak, signaling viral activity days before visible signs appear. The condition is highly contagious through saliva and close contact, requiring caution during outbreaks and shared items. In Korean dermatology clinics, early antiviral therapy and precise differential diagnosis help distinguish it from impetigo or angular cheilitis.
Antiviral medications such as acyclovir, valacyclovir, and famciclovir shorten symptoms and reduce contagiousness when started promptly within the first 24 to 48 hours. Topical antivirals can be effective for mild cases, while systemic treatment is often needed for frequent recurrences or severe outbreaks. Besides medication, supportive skincare with gentle cleansers and fragrance-free lip balms protects the healing skin and minimizes irritation. During healing, sun protection helps prevent post-inflammatory changes and reduces the risk of scar formation.
Triggers of lip herpes
Outbreak frequency is influenced by immune status, stress levels, sleep quality, and recent illnesses, all of which can tip the balance toward reactivation. Sun exposure is a well-known trigger, particularly for individuals with a history of perioral lesions and darker skin types. Hormonal fluctuations, such as those occurring with puberty, pregnancy, or menstrual cycles, can also precipitate recurrences. Lifestyle factors like smoking and excessive alcohol can modulate immune responses and contribute to symptom onset.
In Korean clinics, comprehensive management includes counseling on triggers and personalized strategies to reduce flare-ups. Patients are advised to avoid sharing utensils, lip products, or towels during active episodes to prevent spread. Protective measures such as broad-spectrum sunscreen on the lips and perioral skin are recommended year-round. Some patients maintain a simple symptom diary to anticipate outbreaks and plan antiviral use accordingly.
Treatments in clinics
Clinical management combines antivirals with dermatologic care to address both the outbreak and future skin health. Early antiviral therapy, ideally within the first 24 hours of symptoms, shortens duration and reduces lesion severity. Recent trends in Korea include integrating personalized skincare plans with medical treatment to minimize scarring and enhance recovery.
After active lesions heal, lasers and skin regeneration modalities can safely improve texture, tone, and elasticity. Non-ablative lasers, microneedling, and platelet-rich plasma are often used in staged plans to minimize downtime. Careful timing is essential to avoid provoking reactivation, and some clinicians may use short antiviral prophylaxis around procedures. These integrated approaches reflect Korea’s dermatology landscape, where antiviral management is combined with aesthetic skin rejuvenation for optimal outcomes.
