Using InterceptCS™ is as easy as 1, 2, 3.

Applies Targeted Heat

Therapy Early

Precisely calibrated thermal energy (exactly 123.8°F) is applied directly to the lip in the prodrome stage. Within three hours of the first sign of tingling.

Activates Immune Support & Halts Outbreak

The localized heat interferes with HSV‑1 virus replication and stimulates the heat shock response, which helps infected cells self-destruct.

Disrupts Viral Replication & Triggers Cell Response

The local immune response is boosted, helping the body contain the virus early – stopping the cold sore from ever surfacing.

Is InterceptCS™ a new technology?

Yes. InterceptCS™ is an innovative, drug-free technology that uses precisely targeted heat therapy at 123.8°F. When applied during the prodrome stage — within the first 2–3 hours of that initial tingle — it disrupts HSV-1 activity and boosts the body’s natural cellular immune response to help prevent cold sore outbreaks before they begin.

What is the Prodrome stage?

The prodrome stage is the very first phase of a cold sore outbreak. It usually begins with a tingling, itching, or tightness around the lip area. This stage typically lasts 2–3 hours and is the critical window when InterceptCS™ works best — applying 123.8°F heat therapy before the cold sore can surface.

Does it work best if I use it early?

Yes. InterceptCS™ works best when used early — during the prodrome stage, within 2–3 hours of the first tingle or tightness. Applying precisely calibrated 123.8°F heat therapy at this stage disrupts HSV-1 activity and helps prevent cold sores before they appear.

Is it safe to use?

Yes. InterceptCS™ has been comfort-tested for safe, everyday use by adults and children. (For children under 12, consult with a healthcare provider before use.)

How long does a treatment take?

Each InterceptCS™ session takes just 5 minutes—making it easy to integrate into your busy daily routine.

What are the disposable treatment activators?

The treatment activators are single-use, medical-grade activators—each calibrated to deliver precise, dermatologist-recommended thermal energy that helps interrupt the virus at the first tingle. These activators are what power each session with your InterceptCS™ device.

Can I use it with other skincare or prescription products?

Yes. InterceptCS™ is a non-invasive, non-medicated device, and is generally safe to use alongside other over-the-counter skincare items. If you’re using prescription treatments, we recommend consulting your healthcare provider first.

What if I’m not satisfied with my purchase?

We stand behind our product with a 90-day satisfaction guarantee and a 2-year limited warranty for peace of mind..
