Red Light Therapy is a non-invasive treatment that uses specific, clinically proven wavelengths of red and near-infrared (NIR) light to enhance cellular function. When this light is absorbed by the mitochondria (the powerhouses of our cells), it helps them produce more energy (ATP). This boost in cellular energy can lead to widespread health benefits, including enhanced healing, reduced inflammation, and skin rejuvenation.

Our cells contain mitochondria, which act as their energy factories. Red and NIR light act as a "supercharger" for these mitochondria. When the light is absorbed, it helps the mitochondria use oxygen more efficiently to produce ATP. This energy boost allows cells to repair themselves, regenerate, and perform their functions more effectively, leading to the health benefits associated with the therapy.

Yes, Red Light Therapy is widely considered to be safe and free of side effects for most people. It is a non-invasive, natural therapy that does not burn or damage the skin. Some users may experience temporary tightness or redness, which typically subsides quickly. We recommend starting with shorter session times to allow your body to acclimate.

The primary difference is their wavelength, which determines how deeply they penetrate the body's tissues.

• Red Light (e.g., 660nm) has a shorter wavelength and is primarily absorbed by the skin. It's ideal for improving skin health, stimulating collagen production, reducing wrinkles, and speeding up wound healing.

• Near-Infrared Light (NIR) (e.g., 850nm) has a longer wavelength that penetrates deeper into tissues, including muscles, joints, and bones. It's highly effective for reducing deep-seated inflammation, alleviating pain, and promoting muscle recovery.
  Our devices combine both to deliver comprehensive benefits.

For best results, consistency is key. We recommend most users start with 10-20 minute sessions, 3-5 times per week. Please consult your user manual for more specific guidelines tailored to different goals and treatment areas.

Yes, we highly recommend it. While there is no evidence that our specific wavelengths are harmful to the eyes, the LEDs are very bright and can cause discomfort. For your safety and comfort, we include a pair of blackout goggles with every device and advise wearing them during treatment. Please avoid looking directly into the LEDs.

The clinically-backed wavelengths used in our devices offer a wide range of benefits, including:

• Enhanced Skin Health: Stimulates collagen and elastin production to reduce wrinkles, fine lines, and improve overall skin tone and texture. It can also help with conditions like acne and psoriasis.

• Pain & Inflammation Relief: Reduces inflammation in joints and muscles, providing relief from arthritis, joint pain, and chronic inflammatory conditions.

• Improved Muscle Recovery: Accelerates muscle repair, reduces soreness after exercise (DOMS), and improves overall athletic performance.

• Increased Circulation: Promotes the formation of new capillaries, which improves blood flow to tissues, delivering more oxygen and nutrients for faster healing.

Decades of scientific research have identified a "therapeutic window" of light wavelengths that have the most significant biological effect on the human body. 660nm (Red) and 850nm (NIR) are consistently shown to be the most effective and bio-active. 660nm is the ideal wavelength for skin absorption, while 850nm is optimal for deeper tissue penetration. We focus on these two peaks to ensure our devices deliver the most potent and effective therapy possible.

Pulsed light therapy involves delivering light in rapid, short bursts rather than as a constant stream (Continuous Wave). This technique is based on the theory that cells can respond more effectively to pulsed light, potentially leading to several advantages:

① Enhanced Cellular Response: Pulsing may give cells a brief moment to process the light energy, preventing adaptation and leading to a stronger therapeutic response.

② Deeper Penetration: Some research suggests that the "off" phase of pulsing can reduce thermal build-up in the tissue, potentially allowing the light to penetrate deeper. Our advanced models include this pulsing feature to give users more control over their therapy.

This depends on your specific goals and the area you wish to treat.

• For targeted treatments like facial rejuvenation or specific joint pain, our smaller, targeted panels are a great choice.

• For whole-body benefits such as improved athletic performance, systemic inflammation reduction, or overall wellness, our full-body panels are recommended.

We prioritize your safety. All of our devices are engineered with advanced shielding to ensure extremely low EMF emissions. At the recommended treatment distance of 6 inches or more, the EMF levels are negligible and fall well within international safety standards.

Maintenance is simple. First, ensure the device is unplugged. Use a soft, dry, or slightly damp cloth to gently wipe the surface and the LEDs. Do not use chemical cleaners, and never allow water to get inside the unit.
