do you dry your cold sore out or keep it moist
However, it is possible that cold sores heal better when they are kept moist. Of course, aciclovir cream will keep it moist as well as having a specific antiviral action. Tea tree oil, or oil from a vitamin A or vitamin C capsule, are other methods of keeping it moist and may reduce inflammation slightly. Be hygienic.Hygiene is important, because you do not want a bacterial infection to move in. 1  Try not to touch the sore with your hands. If you apply any cream or oil to the sore, use a new cotton-wool bud each time. 2  To wash the area, dab it gently with a moistened tissue. 3  Do not apply any disinfectant, because this may be too harsh for the damaged skin.
