What is Red Light Therapy?

Red Light Therapy (RLT) is a science-backed, non-invasive treatment that uses specific wavelengths of light to penetrate the skin and stimulate cellular repair, reduce inflammation, and enhance overall wellness. CELLER8’s advanced red light technology utilizes a broad spectrum of therapeutic wavelengths 480nm, 630nm, 660nm, 810nm, 830nm, 850nm, and 940nm to deliver full-spectrum benefits for the body and mind.

What is Red Light Therapy Commonly Used For?

Red light therapy (RLT), also known as photobiomodulation (PBM), is a non-invasive treatment that uses low-level red and near-infrared light to stimulate cellular function. It is widely used for anti-aging and skin benefits by enhancing collagen production, improving skin elasticity, and reducing wrinkles and fine lines. PBM also accelerates cellular repair, reduces inflammation, and promotes an even skin tone, helping to combat signs of aging and support overall skin health. Additionally, it can aid in wound healing, hair regrowth, and muscle recovery.

How Red Light Therapy Works

Red light therapy works by delivering specific wavelengths of red and near-infrared light to the body, which stimulates your cells particularly the mitochondria, known as the energy factories of your cells. One key enzyme in the mitochondria, called cytochrome c oxidase, absorbs this light and becomes more active. This leads to a boost in the production of ATP, the main energy currency of the body, giving your cells more fuel to heal, repair, and perform their functions better.

 

Another important effect is the release of nitric oxide, a gas that can build up and block cellular energy production. Red light therapy helps displace this nitric oxide, allowing mitochondria to work more efficiently while also improving blood flow and oxygen delivery throughout the body.

 

Red light therapy also helps balance calcium levels through light-sensitive ion channels and activates signaling molecules like reactive oxygen species (ROS), cAMP, and nitric oxide. These signals trigger important biological responses such as reducing inflammation, fighting oxidative stress, boosting antioxidant production, and activating genes involved in healing and regeneration.

 

Stem cells and other regenerative cells respond especially well to this light, which helps explain why red light therapy can support everything from faster injury recovery and muscle repair to skin rejuvenation and even improved brain function. Unlike UV light, it doesn’t damage DNA or burn the skin, making it a safe, non-invasive tool to help the body heal, repair, and thrive from the inside out.

Red Light Therapy (PBM) FDA Approvals

2002 – FDA cleared PBM devices for relief of minor muscle and joint pain, arthritis, muscle spasms, and increasing local blood circulation.

2003 – FDA cleared PBM for muscle relaxation and stiffness reduction as an adjunctive therapy in physical medicine.

2009 – FDA cleared low-level light therapy (LLLT), a form of PBM, for treatment of carpal tunnel syndrome.

2010 – FDA cleared laser and LED caps (e.g., HairMax, iRestore) for treatment of hair loss (androgenetic alopecia) in both men and women.

2013 – FDA cleared PBM for reducing pain and stiffness associated with knee osteoarthritis.

2018–present – Continued FDA clearance for red light devices for wrinkle reduction, wound healing, and supporting recovery after cosmetic procedures (depending on device and claim).

Will Red Light Therapy Work for My Condition?

Yes. While red light therapy is not condition-specific, it works by supporting your body’s natural healing processes at a cellular level. Red and near-infrared light penetrate the skin and stimulate your mitochondria, the energy centres of your cells, helping to boost ATP production, reduce inflammation, and improve blood flow. By creating a more energized and balanced internal environment, red light therapy can support recovery, reduce pain, and improve overall function. Whether you're managing skin issues, muscle or joint pain, slow healing, fatigue, or just aiming to optimise your wellness, red light therapy helps your body restore and thrive from the inside out.

Understanding Red Light Specifications

Wavelengths (nm)

CELLER8 uses a precise combination of seven therapeutic wavelengths to target multiple layers of tissue:

 

480nm (Blue Light) – Supports skin health by targeting blemishes and promoting a balanced complexion.


630nm & 660nm (Red Light) – Penetrates the skin to stimulate collagen production, improve circulation, and accelerate healing.


810nm, 830nm & 850nm (Near-Infrared Light - NIR) – Reaches deeper tissues, muscles, and joints, promoting recovery and reducing pain.


940nm (Deep Near-Infrared Light) – Enhances oxygen delivery, boosts circulation, and supports nerve function at a cellular level.

Irradiance (Power Output)

Irradiance (measured in mW/cm²) determines how much energy reaches your cells. Higher irradiance means deeper penetration, ensuring your body absorbs enough light for meaningful results.

 

CELLER8 delivers high-power irradiance for optimal effectiveness, while many brands exaggerate their power claims or use weak LEDs that fail to deliver true therapeutic benefits.

Beam Angle

Beam angle affects how efficiently the light spreads over the treatment area. CELLER8 devices are engineered with an optimal beam angle to ensure deep penetration while covering a large surface area striking the perfect balance between focused intensity and full-body coverage.

Flicker-Free & Low EMF

Many cheap red light panels flicker, which can cause eye strain and headaches. CELLER8 panels are completely flicker-free, ensuring a comfortable experience.

 

Additionally, low EMF (Electromagnetic Fields) is crucial for safety. Some poorly designed panels emit high EMF levels, which can interfere with your body's natural functions. CELLER8 is engineered to be low-EMF for a safer and cleaner therapy session.

Pulsing & Continuous Light 

Some studies suggest that pulsed light may enhance biological effects, particularly for brain health and recovery. CELLER8 gives you both pulsed and continuous wave options, allowing you to customize your therapy based on your needs.

Red Light Therapy Contraindications & Cautions

Pregnant Women – While no studies suggest harm, it's best to consult a healthcare provider before using red light therapy during pregnancy.

 

People with Photosensitivity – If you have light sensitivity disorders (e.g., lupus, porphyria) or take medications that increase photosensitivity (e.g., certain antibiotics, acne medications, or chemotherapy drugs), consult your doctor before use.

 

Individuals with Active Skin Cancer or Tumors – Red light therapy may stimulate cell activity, so it should be avoided over cancerous lesions unless advised by a medical professional.

 

People with Epilepsy or Seizure Disorders – Some individuals with epilepsy may be sensitive to bright light exposure. If you have a history of photosensitive epilepsy, consult a doctor before use.

 

Those with Retinal Conditions or Recent Eye Surgery – While red light therapy can be beneficial for eye health, direct exposure to strong LEDs should be avoided after eye surgery or if you have retinal damage. Always use protective eyewear if needed.
