Is the sun causing your cold sores to come out?

A study in the United States looked into the effect of sunscreen application on the incidence of cold sores. Of 38 patients, who recurrently suffer from Herpes simplex infections, 27 developed cold sores after exposure to UV radiation. In contrast, after the application of protective sunscreen, none of the patients developed cold sores.

Therefore, beyond limiting skin-damaging effects, sunscreen may be effective in the prevention of sunlight-induced recurrent eruptions. For more go to the link here and type “herpes.” http://ow.ly/P0wZc
