How It Works

Varichrome™ Pro

Proven therapy that prompts the body to heal.


How Does The Therapy Work?

The short answer:

The body heals itself; the therapy prompts a restart.

Red and infrared wavelengths remain the most studied; typically examining the effects of one wavelength per study. 5000+ studies show that many mechanisms may be involved in relieving pain, promoting relaxation, reducing inflammation, and a myriad of other improvements. Often cited, the wavelengths in the red and infrared spectrum may be selected for their ability to penetrate the skin to stimulate deeper tissues.


The Varichrome Pro Preset #1 varies the wavelength in the most cited visible range of 630 to 690nm range. The practitioner can use the manual mode to emit a non-varying wavelength range with a peak from about 430 to 690nm. The fixed wavelengths may be used to observe tissues of different colors, such as in wounds.

Could a 10-second video be worth 10,000 words?

  • 7 pre-programmed ranges cover portions of the spectrum found to help the body improve impaired functions.

  • Like everything in medicine, you have try it to learn if it will "work" for the individual patient.​

  • Varying the wavelength during therapy efficiently improves the likelihood of prompting the body to resume healing.​

  • The practitioner monitors for a physiological response during therapy. Reports of pain relief often arrive later.​

  • The Varichrome Pro is now commercially available. Contact PhotoMed for details.

Introducing the Varichrome™ Pro

The Varichrome™ Pro helps the practitioner promote their patient's return to wellness via personalized therapy. It's like having hundreds of single-output devices.

Easy to use

  • The practitioner personalizes the therapy by adjusting the settings during therapy.

  • The Varichrome Pro selectively emits 260 wavelengths, a few at a time, with no missing wavelengths. (430-690nm)

  • 7 Preset Selections automatically vary the wavelength during therapy to increase the likelihood of prompting relief.

  • Adjust the frequency from continuous to 500Hz.

The practitioner now has access to wavelengths throughout the visible spectrum. The gentle beam of selected photons prompts the return of balance and normal healing.

The practitioner adjusts the analog controls to efficiently find the stimulation that meets the patient's needs. The logic is straightforward - try the most likely candidate wavelengths first. 2 visits are enough to objectively determine whether the therapy works for that injury, or not.

Like with other therapies, you have to try it to learn if the patient responds. The practitioner can now test 1000s of combinations in minutes. That's efficiency. Only with the Varichrome Pro.

Photons from the Varichrome™ Pro gently stimulate the skin with ever-changing wavelengths of visible light. The body responds by resuming its balancing and healing processes.

Wellness involves the coordination among the basic functions:

   · sensory

   · motor

   · skin-temperature regulation.


The practitioner can objectively determine that therapy is working for the sensory and motor systems. However, the before and after documentation doesn't tell precisely when the body responded.

The therapy, like many non-invasive therapies, prompts the body to complete its healing tasks. One goal may be to “unstick” a “stuck” basic function or healing. Such as from a “plateau” in the progress after an injury.

The Preset Selections of the Varichrome Pro became efficient via data from real-time recordings in 7 feasibility studies. Thermal imaging connected the dots between the stimulation parameters and the responses.


The data shows that the responses are normal in every respect: the delay in the coldness state accounts for the unexpectedness of the event.

​This 50-year old man's hands have persisted uncomfortably cold for years. His hands resumed their normal modulation after a single stimulation by variable-wavelength therapy.

Could the Stimulation be getting our attention?

The short answer:

The body heals itself; the therapy prompts a restart.

Speculation, of course, the photons with varying wavelength stimulate the skin with ever-changing signals and the brain responds.


The process shares similarities with touch and hearing. The brain, nervous system, and skin or ears are "tuned" to simultaneously detect and respond to a myriad of different signals. For example, unexpectedly hearing your name at a football game or intentionally attempting to talk with another person in a crowded room. It's the task of bodily systems to improve communications.

Bringing attention to an injured site on the skin might prompt the completion of tasks that had been stalled for years. Some patients provide the answer as they blurt out, I feel normal again.

Finally, would the return to normal functioning (healing) be noticed if it happened at the right time?

2 Visits to Learn If The Therapy Might "Work"

The real-time data and recordings from 7 feasibility studies across 5 states helped to make the therapy more efficient.

Today, 2 visits without any response or relief are typically enough to suggest that it is time to try a different therapy.

What Makes the Varichrome™Pro So Versatile?

Could the variability of the stimulation be more like a video than a still image?

The Varichrome Pro selectively emits photons with wavelengths throughout the visible spectrum (430-690nm), a few wavelengths at a time.

With no missing wavelengths.

Its analog controls let the practitioner vary the wavelength and frequency during therapy.

  • 7 Pre-programmed selections:

  1. #1-5 span the visible spectrum

  2. #6 yellow

  3. #7 spans 440-680nm

  • Adjustable-rate of wavelength variation in programmed selections: 4 - 26nm/second

  • Manual range: 430-690nm

  • Frequency: continuous to 500Hz

  • Dimensions: L x W x H: 6.6 x 3.5 x 1.8 inches (Control unit w/o knobs)

  • Weight: <2 lbs

  • Charging Supply: 12VDC @ 6Watts,  charging time ~ 4hrs.

  • Operating time: 2hrs @ max intensity (external battery pack)

  • Working distance and diameter: 1.5 inches, 1.5 inches

The Varichrome Pro is a Class II physical medical device.
