Your lip balm is triggering cold sores. Labisan won't.
Distance runners face a specific cold sore risk most sport brands ignore. UV exposure during long runs is the primary documented trigger for HSV-1 reactivation: herpes labialis outbreaks increase significantly after sustained UV exposure without mineral-barrier protection. Compound this with the immunosuppressive effect of high-mileage training and race-day cortisol, and you have a population with chronically elevated reactivation risk. Most sport lip balms make it worse. Menthol and camphor irritate lip mucosa and can trigger the inflammatory cascade preceding an outbreak. Labisan's 22% zinc oxide delivers a certified SPF 20 mineral barrier with manuka oil and graviola annonacin for antimicrobial support. The 22:1 graviola immune capsules (8000mg daily equivalent) address the systemic suppression side. EU pharma grade since 1931.
