Gently apply a small amount of the film forming serum on the fever blister so that it adequately covers all lesions and a margin of healthy skin surrounding them. After a few minutes the white serum forms a protective and transparent film over the fever blister. The serum can be reapplied, if necessary, every 3-4 hours until the fever blister is completely healed. The film can be removed, if necessary, with warm water.
You can use Herpatch Serum at any stage of the outbreak. However, we suggest applying it at first sign of an outbreak.
