The Science of Light: How It Stops a Cold Sore in Its Tracks

It appears to be magic, but it is pure science. Our red light therapy devices utilize concentrated, specific wavelengths of light that penetrate the skin to work at the cellular level. It is the same tech scientists studied and used by dermatologists for its healing potential.

Here's why our device provides immediate relief and accelerates healing:

Heals Faster: The light energy is absorbed by your cells, which boosts their energy (ATP) levels. The fuel for the cells then speeds up the normal repair and regeneration process, cutting the duration of the outbreak dramatically.

Provides Instant Relief from Pain: Red light has potent anti-inflammatory chemicals. It soothes inflamed nerve endings and reduces the swelling and inflammation that cause the characteristic pain and discomfort of a cold sore.

Boosts Local Skin Immunity: By enhancing circulation and cell health in the treated zone, the device can assist in making your skin stronger. Most find that regular use at the onset of an outbreak makes the frequency and severity of future episodes fewer and far between over time.

Precision Tip to Treat Specifically: The device comes with a precise tip that allows you to apply the treatment light to the cold sore directly without coming into contact with the rest of the skin around it.

Frequently Asked Questions (FAQ)

We want you to feel comfortable using this new technology. Below are some frequently asked questions and answers.

Q1: When is the best time to use the device?

A: The absolute best time is the very first showing of an outbreak—the "tingle stage." Starting treatment immediately will significantly reduce the severity and duration of the cold sore, and in some cases, is even able to prevent a full-blown blister. You can also use it at any time to speed healing and reduce pain.

Q2: Is the red light therapy device safe to use on my lips?

A: Yes, it is completely safe, painless, and non-surgical. It is based on natural energy of light, not chemicals or drugs, and will not dry out or irritate your skin. It is FDA-approved technology for application to skin.

Q3: How do I use it?

A: It's extremely simple. Just place the tip of the unit directly on the cold sore or the area you experience tingling. Hold for the duration of one treatment cycle (typically up to 3 minutes). Repeat 2-3 times per day for best results.

Q4: How long until I see results?

A: Most will find that they have relief from pain by the second or first session. You will discover the cold sore heals much faster than it might have otherwise—often half the normal time. Blisters are smaller and dry up faster.

Q5: Will this unit do anything else?

A: While it is specifically designed and optimized for canker sores (fever blisters) and cold sores, the curing therapeutic red light also helps heal minor pimples, scrapes, or cuts.
