Disrupts Viral Replication & Triggers Cell Response
Activates Immune Support & Halts Outbreak
Applies Targeted Heat Therapy Early
The local immune response is boosted, helping the body contain the virus early — stopping the cold sore from ever surfacing.
The localized heat interferes with HSV‑1 virus replication and stimulates the heat shock response, which helps infected cells self-destruct.
Precisely calibrated thermal energy (exactly 123.8°F) is applied directly to the lip at the first sign of tingling.

“Intercept CS device and activators have worked fantastically for me to stop my coldsores. I use it the moment I feel the pain or tingle of an oncoming cold sore and it works so well I haven’t found anything on the market that works as well. It literally stops them dead in their tracks. I would highly recommend them."
