Cold Sores (Herpes Labialis)
Cold sores are recurrent blistering outbreaks on or around the lips caused by HSV-1. After initial infection, the virus remains dormant and can reactivate periodically.
When to Book
Book a visit if a skin concern is new, spreading, painful, not improving with over-the-counter care, or changing in appearance.
Symptoms
Tingling prodrome followed by grouped vesicles at the lip border that rupture, ulcerate, and crust over in seven to ten days. Triggered by stress, UV, and illness.
Causes & Risk Factors
HSV-1 spreads through direct contact. Most people acquire it in childhood. Immunosuppression and UV exposure trigger reactivation.
How We Evaluate
Usually clinical. Viral PCR confirms uncertain cases. We assess outbreak frequency to determine whether suppressive therapy is appropriate.
Treatment Options
Oral valacyclovir started within 24 hours of prodrome shortens duration. Daily suppressive therapy reduces frequency in patients with six-plus episodes per year. Our North Miami Beach team provides early-treatment prescriptions.
When It Is Urgent
Seek immediate care if cold sores spread near the eyes, if immunosuppressed with widespread lesions, or if a newborn is exposed.
Frequently Asked Questions
Do I need a referral to see a dermatology provider?
No referral is required at Nomi Beach Health. You can book directly for any skin, hair, or nail concern.
What should I expect at my first dermatology visit?
We perform a focused skin examination, review your history, and discuss a treatment plan the same day. Bring a list of current medications and any photos of how the condition has changed.
How long does it take for skin treatments to work?
Timelines vary. Topical treatments for eczema or acne often improve in two to six weeks. Chronic conditions like psoriasis may need several months of consistent therapy.
Will my skin condition come back after treatment?
Many skin conditions are chronic and managed rather than cured. We create maintenance plans to minimize flare-ups and guide you on when to resume active treatment.
Do you accept insurance for dermatology visits?
Yes. We accept most major insurance plans. Contact our office to confirm your specific plan before scheduling.
