Why Red Light Therapy is One of the Best Healing Tools

Benifits of red light therapy

Red light therapy, also known as photobiomodulation or LED light therapy, is considered a safe, painless, non-invasive, and drug-free form of treatment for healing the skin and body.

Red light can penetrate the body 8-10 millimeters into the skin — reaching deep into tissues, muscles, and bone.

Many studies indicate that red light therapy has numerous potential health benefits, including but not limited to: improved mitochondrial function, improved blood circulation, muscle recovery, and collagen production, as well as decreased pain and radiant skin.

Red Light therapy also has anti-inflammatory effects that may help heal a wide range of issues from the surface of the skin all the way down to the bone.

LED red light therapy products to use a patent-pending combination of light within the 625nm – 900nm range, which are the most effective for healing wounds and various skin conditions.

How does red light therapy devices work?

Red light is bioactive and can have profound effects on your body by increasing mitochondrial function – the ability to produce cellular energy. The more cellular energy production, the better the body functions as a whole. Red light is especially powerful because it can penetrate 8-10 millimeters into the skin, reaching below the dermis layer and into the subcutaneous fatty layer, which stimulates collagen and elastin production, and accelerates healing. Note that this type of treatment is extremely safe, non-invasive, and drug-free.

What are the benefits of red light therapy devices?

NASA developed led red light therapy for plant growth experiments. Over the years, NASA researchers were able to take this space technology and adapt it for medical applications, such as healing tumors, skin ulcers, serious burns, and oral mucositis.

Astronauts also found a lot of success using red light therapy to reduce pain, accelerate wound healing, and prevent muscle or bone atrophy. There are now over 3,000 peer-reviewed studies that illustrate red light therapy’s seemingly magical ability to heal the skin and body. 

Key Benefits:

  • Enhanced blood circulation
  • Anti-inflammatory effects(3)
  • Increased muscle recovery
  • Increased collagen production
  • Radiant skin
  • Reduces scars, wrinkles, & fine lines
  • Speeds wound healing
  • Enhanced fertility
  • Increased testosterone
  • Decreases pain

Which wavelengths of red light are the most effective?

Resounding research over the past 40+ years has shown that wavelengths between 625nm and 900nm are the most effective for healing wounds and other skin conditions. At the lower end of this spectrum, 630 and 660nm have the greatest efficacy because your mitochondria can absorb these red wavelengths easily. This is also where the absorption of cytochrome c oxidase peaks, which is one of the key mechanisms of red light therapy.

660nm is believed to be the best single wavelength for the stimulation and healing of damaged or abnormal human cell tissue. This is because of its compatibility with cells in the body. Healthy cells emit wavelengths between 600nm and 725nm, on average, whereas unhealthy cells emit a shorter wavelength. 660nm is the midpoint and appears to be closer to the resonant frequency of cell tissue.

Choosing the Best Red Light Therapy Device

Fortunately, you no longer have to pay for expensive red light therapy device sessions at salons or medical offices; this form of treatment is now accessible for at-home use or on the go. Given the wide variety of red light and near-infrared devices that are on the market, the most important factor to consider is the wavelength of light emitted. In order to reach the mitochondria, you want to make sure that you invest in a red light therapy device that emits light in the 630-660nm range.

Want to take your healing even further? Polychromatic red light therapy device allows you to use multiple wavelengths of light at the same time to heal the body. In addition to 630 and 660nm (red light), devices that also emit 850 (near-infrared) can help you reach deeper into soft tissues, muscles, joints, and bones. 580nm (yellow or amber light therapy) can also be used to specifically target the surface of your skin.   For full skin-to-bone healing, consider using a TrueLight LED light therapy device.

The Science & Benefits Behind Red Light Therapy

According to Ilyas, who practices at Schweiger Dermatology Group in Pennsylvania, data shows that red light therapy can penetrate the skin deeply up to 6 millimeters.

Red light therapy treats acne, wound healing, hair regrowth, and anti-aging, like plumping up fine lines and wrinkles. “It is believed to work by activating signaling pathways between cells. It has not been shown to damage the DNA of cells the way UV light does,” says Ilyas.

Ilyas’ number-one tip is carefully researching options to ensure they fit your lifestyle, budget, and skincare goals. Don’t worry: I carefully vetted every product on this list to bring you only the best red light skin therapy in the game.


The Pennsylvania-based doctor suggests buying a practical and user-friendly red light therapy device, such as a well-fitting face mask, like Ora LED Light Energy Mask and Skin Gym Wrinklit LED Mask. However, Ilyas notes that just because one face mask is popular and fits someone nicely doesn’t mean it’s the perfect fit for your face.

 If you’re concerned a red light skin therapy device won’t accommodate your features, look for a face mask with adjustable straps, such as the Higher Dose Red Light Face Mask and MZ Skin LED 2.0 LightMAX Supercharged LED Mask.


She says three-panel options, like Trophy Skin RejuvaliteMD Red Light Therapy, are simple to use but not ideal if kids run in and out of the room while you’re using it. You can also use a single-panel red light therapy device, including the Celluma PRO, which provides full coverage on your face like a three-panel option, just with a different aesthetic. Regardless of which model you opt for, panel red light therapy machine take up quite a bit of space, so if you live in a tiny studio, you can opt for the third option.

There are a number of benefits of Red Light Therapy machine. Red Light Therapy combines intense red light (650nm) and near-infrared (850nm) wavelengths to offer you optimal color light therapy. Red Light provides the most proven and effective therapeutic wavelengths to the entire body. It reduces oxidative stress and stimulates the production of ATP.
