Conditions

Cold Sores

Brief summary

Focus Consumer Healthcare has developed Herpecin L. Herpecin L combines many different ingredients hypothesized to promote quick healing and symptom reduction from cold sores.

Interventions

OTHERHerpecin L

Participants in the Herpecin L arm will use the test product daily as a preventive product by applying the product twice daily. Also, participants will be told they can reapply the product if going outside into the cold, wind, or sun. If participants in the Herpecin L arm do experience a cold sore or fever blister, they will be instructed to use the product at the first sign of the cold sore and then at least four more times during the day until the cold sore is gone (they can use the product more often if they plan to go outside into the cold, sun, or wind).
