Cold sore Q&A

What does daily cold sore suppression mean?

Daily cold sore suppression means intercepting HSV-1's two primary reactivation triggers, UV radiation and mucosal barrier breakdown, before the virus can replicate to the surface. Most lip balms accelerate this cycle: menthol and camphor are vasodilators that dry the lip mucosa and increase outbreak frequency. Labisan's 22% zinc oxide mineral formula delivers SPF 20 blockade without chemical penetration sensitisers, while manuka oil and graviola annonacin reinforce local immune surveillance. The 22:1 graviola capsule extends suppression systemically, delivering 8,000mg daily equivalent.

Evidence

  • 22% zinc oxide provides broad-spectrum mineral UV blockade that interrupts the photoreactivation pathway that triggers herpes labialis outbreaks.
  • Menthol and camphor, present in most mainstream lip balms, compromise lip mucosa integrity and are documented vasodilators that worsen cold sore frequency.
  • Graviola annonacin at a 22:1 extract concentration (8,000mg fresh-fruit daily equivalent) supports systemic immune modulation relevant to HSV-1 suppression.
