Frequently Asked Questions

Another term for red light therapy is photobiomodulation.
If you search “photobiomodulation” on PubMed, you’ll find over 10,000
scientific studies. Labs and universities around the world have been
investigating how red light affects a wide range of diseases and conditions.
The findings? Overwhelmingly positive.

Red light therapy is a completely non-invasive treatment. Its “side effects”
are all positive, such as improved skin tone, firmer texture, smoother lines,
and reduced stretch marks, thanks to boosted collagen production at
635nm and 660nm wavelengths. According to the FDA, LED phototherapy is
considered a non-significant risk device under low-level light therapy.

No; in fact, it can be beneficial for eye health, as long as you use it
sensibly.

  • You should not feel any pain when the light shines toward your eyes.
  • If it does hurt, the light is likely too strong or too close. Simply move it
    farther away until you can gaze in its direction comfortably.
  • Short sessions of about 5 minutes are enough.
  • Doing it before 9 a.m. is considered the best protocol for eye health.

In fact, studies on these same wavelengths have even shown potential
healing benefits and improvements in vision.

Red and near-infrared wavelengths penetrate the skin and reach the cells,
where they boost mitochondrial energy production. This triggers cellular
reactions that support repair, reduce inflammation, and improve overall
function.

This is going to sound ridiculous, but…
Red light therapy helps with almost everything.

  • Pain relief
  • Eye health
  • Better sleep
  • Younger-looking skin
  • Improved sports performance
  • Faster recovery from exercise or injury
  • Thicker, longer hair
  • Optimized hormone production
    … and so much more.

Why does it work for so many different things?
Because of the way it affects your body at the cellular level.

Red and near-infrared light therapy is one of the safest wellness tools
available, backed by thousands of studies and with almost ZERO reported
side effects.
In rare cases, excessive exposure may cause temporary discomfort, but this
typically requires prolonged, unusually high doses well beyond
recommended use.
This safety is rooted in biology: Red and near infra red wavelengths are part of the natural solar spectrum that humans have evolved with for millions of
years.

For most people, red light therapy is considered safe. It can generally be
used during pregnancy and is usually compatible with most types of
implants. However, if you are undergoing cancer treatment, taking
photosensitive medications, or dealing with any other serious health
concern, it’s always best to consult your doctor before starting.

Yes, red light therapy is safe for children and can support their overall
health. It’s also helpful for minor injuries and everyday bumps or scrapes.
You can use it for kids in the same way you would for adults, but it’s best to
start with shorter sessions and adjust based on how they respond.

For best results, red light therapy should be done on clean, bare skin. It’s
ideal to use it before applying makeup, moisturizers, or other skincare
products, and with as little clothing as possible. This allows the light to
penetrate and be absorbed by your skin without unnecessary barriers.

Red light (660nm) is visible and penetrates about 1–2 mm into the skin,
targeting surface tissues. Near-infrared light (850nm) is almost invisible and
penetrates deeper (2–3 mm), reaching cells, muscles and joints. Our
devices use a 2:1 ration of NIR:R to blend both wavelengths to deliver
benefits at both surface and deeper levels.

Irradiance is the power of electromagnetic radiation falling on a surface per
unit area. It is an instantaneous measurement of the radiant flux (energy per
time) incident on a surface, with the standard International System (SI) unit
being watts per square meter (W/m²)

Red light therapy is ultimately a numbers game. The benefits you feel come
down to how many photons your cells can actually absorb.

  • Not every photon makes it deep into tissue, many bounce off, scatter, or
    get absorbed by the surface.
  • Irradiance tells you how many photons are available in the first place.
  • The higher the irradiance, the more photons your body has to work with.
  • More photons = better chance of reaching deep tissue and triggering
    real biological change.

One of the most important factors to consider when buying a wellness
device is the amount of EMF generated by the product.
O’Ra products are carefully engineered with very low EMF output, this
ensures you can enjoy the benefits without adding unnecessary exposure
to your environment.
