For climbers and alpinists

Cold sore prevention for climbers and alpinists

UV intensity increases roughly 10% per 1,000 metres of altitude. On a Dolomite ridge or a Mont Blanc traverse you are absorbing two to three times the sea-level UV dose, and your lips carry that load unprotected. HSV-1, the virus behind herpes labialis, reactivates directly in response to UV exposure and physical stress. Most climbing lip balms compound the problem: menthol and camphor, staples of outdoor formulas like Carmex and Blistex, are documented HSV-1 irritants that extend outbreak duration by three to five days. Labisan uses 22% zinc oxide, a mineral filter that reflects UV without chemical sensitisation, plus manuka oil for antimicrobial barrier protection and graviola fruit extract for immune support. Austrian pharma-grade since 1931.
