Identifying Cold Sores: Visual Signs and Symptoms
What Cold Sores Look Like: 5 Key Stages
Cold sores progress through distinct visual stages, typically lasting 7-10 days. Initially, you may experience tingling, itching or burning sensations around the lip area before any visible signs appear. Small, fluid-filled blisters then develop, usually clustered together on or around the lips. These blisters appear red and swollen, often feeling tender to touch.
During the weeping stage, blisters burst and release clear fluid, forming shallow ulcers. This phase represents the most contagious period. Subsequently, yellow-brown crusts or scabs form over the affected area as healing begins. Finally, the scab naturally falls away, revealing new skin underneath.
Sun Protection: Your First Line of Defence
UV radiation represents one of the most common cold sore triggers. The NHS recommends applying broad-spectrum SPF 30+ lip protection before any sun exposure. Choose lip balms containing zinc oxide or titanium dioxide for optimal UV blocking. Reapply every two hours, particularly after eating or drinking.
Wide-brimmed hats provide additional facial protection, whilst seeking shade during peak UV hours (11am-3pm) reduces trigger exposure. Consider wearing sunglasses to prevent squinting, which may stress facial skin and potentially trigger outbreaks in susceptible individuals.
When Prevention Fails: Treatment Options
Despite preventive measures, cold sores may still occur. EverydayMeds offers several NHS-approved treatments including Aciclovir 400mg tablets and Aciclovir 5% cream. These antiviral medications work most effectively when started during the tingling stage, before blisters fully develop.
Valaciclovir 500mg tablets represent an alternative option, requiring less frequent dosing than standard aciclovir. Topical treatments like aciclovir cream may help reduce healing time when applied early and regularly. Always consult healthcare professionals before starting new treatments, particularly if you experience frequent outbreaks.
