Heal summertime cold sores fast!
People tend to get more cold sores in summer, because the virus can be activated by heat and sunlight. So when you feel that telltale tingle: Get a vitamin D gel capsule, prick it open with a clean pin, and put a drop of the liquid on your cold sore. Dermatologist Joshua Zeichner is from Mount Sinai Hospital in New York City… and he says the anti-inflammatory properties in vitamin D can reduce the severity of cold sores, and help them heal faster.
