N1 COLD SORE CREAM  – Fast, effective and easily tolerated treatment of cold sore

Scientifically proven effect: The N1 COLD SORE CREAM is based on a patented composition of natural fatty acids (F.A.G,®) for the treatment of recurring herpes infections with blistering in the lip area.

The rapid effectiveness of the cream has been proven by a clinical study. This showed that the duration of pain when using the N1 COLD SORE CREAM was on average 30 times shorter and the duration of symptoms 29 times shorter than a cream with the active ingredient acyclovir. In 80% of the test persons, cold sores never formed in the first place. Overall, healing was on average twice as fast as with the acyclovir cream.*

The N1 COLD SORE CREAM controls inflammation by restricting the spread of the virus and creating a barrier that prevents viruses from entering the cell. The time in which the symptoms of the disease persist is shortened and virus replication is limited. If used in good time, the formation of cold sores can be completely prevented.

Our N1 COLD SORE CREAM is extremely easy to use, effective and also cortisone-free.
