Why Red-Light Therapy?

Light is essential to life. But not all light is created equal.

Natural sunlight energizes the body, allowing us to thrive and function optimally. UV light and blue light, on the other hand, can damage our cells and negatively affect our health.

Red light therapy, also known as photobiomodulation (PBMT) or low-level laser therapy (LLLT), releases a healthy spectrum of red and near-infrared light. Red light therapy works similarly to sunlight – but without the harmful UV rays. Our skin cells actively absorb this beneficial light which is used to enhance our overall wellbeing.

Red light therapy has been used for over 50 years worldwide by wellness centres, professional athletes, and beauty clinics for a wide range of health-promoting benefits.

Red light therapy is backed by science and has been effectively used to:

  • Enhance sports performance and recovery
  • Manage chronic pain (including arthritis)
  • Combat fine lines and wrinkles
  • Treat skin damage
  • Boost wound healing and tissue repair
  • Improve sleep quality
  • Aid neurological conditions

How Does it Work?

Specialized red light technology devices, like Ruby LED, emit a combination of both red light and near-infrared light (NIR).

Red light has a wavelength of about 660nm which is happily soaked up by the skin cells. Near-infrared light with a wavelength of 850nm, penetrates slightly deeper, into the tissues. These dual wavelengths work together to stimulate natural biological processes within the targeted region of the body.

Red light therapy has been used to effectively energize the cells and stimulate blood flow which can lead to a whole range of health benefits.

Is it Safe? 


Red light therapy has no reported adverse side-effects.

The light produced by Ruby LED devices is safe, effective, and painless.

As your skin soaks up the beneficial light, you will feel a slightly warm sensation due to the non-visible infrared light. This is completely normal and should feel no different than laying out on a relaxing summer’s day.

Frequently Asked Questions

What are the side effects of red light therapy?

Generally, red light therapy is harmless and painless as it mimics the natural rays of the sun minus the harmful UV rays. However, it is to be seen just like other light treatment options as infrared therapy and red LED therapy that can have consequences for the eyes. Dizziness, headaches, irritability, eye strain, and other mild visual side effects are not unusual complaints, especially for those new to red light therapy. For any discomfort or pain, it is best to consult with a health professional immediately.

Can you overuse red light therapy?

The use of red light therapy would be best started gradually, especially for first-timers. In general, too much exposure to any kind of light therapy can lead to skin damage.

Is it safe to use red light therapy every day?

Yes, red light therapy is safe to be used every day. For first time users, it is best to start with short sessions and progress to longer intervals as your body gets used to the exposure and the heat. 

Can red light therapy damage the eyes?

As with any other light therapy, staring straight into a light source for a prolonged period of time can cause eye strain. Wear eye protective gear such as sunglasses or goggles if you have eye sensitivity or to prevent straining your eyes during long red light therapy sessions.

Can you eat before doing red light therapy?

Yes, make sure not to do red light therapy on an empty stomach as sessions like this can be a little dehydrating. Prepare water or rehydrating drinks after the red light therapy to avoid dehydration, especially for sessions that last for more than an hour.

How many sessions of red light therapy does it take to see results?

The effectiveness of red light therapy depends from person to person. It could be a week or two for some while others might see the effects after a month or so. The results may vary from person to person and it can also be affected by different factors such as the duration of red light therapy sessions and frequency of sessions.
