The Science behind Hello Face
WHAT IS RED LIGHT THERAPY?
- Red light therapy, also known as photobiological regulation (PBM), has been shown to be a non-invasive, non-toxic, beneficial, and non-invasive form of treatment with few side effects.
- The principle of infrared physiotherapy is mainly the thermal effect (that is, heat), when the infrared radiation to our body, due to the strong penetration of infrared, it can reach the molecular or atomic gap, so that the vibration of molecules, atoms, spacing, resulting in increased thermal movement energy. Can cause local blood circulation to improve, tissue nutrition metabolism to strengthen, accelerate local exudate absorption, thus promoting the regression of swelling. At the same time, the heat action can also reduce the skeletal muscle tension around the joint, relieve muscle spasm, and reduce the excitability of the sensory nerve, interfere with the pain valve, conducive to pain relief.
- The scientists found that red and near-infrared (NIR) wavelengths are particularly suitable for mitochondria, the cell's main energy producers, as they penetrate the skin. Red and near-infrared wavelengths stimulate mitochondria, causing them to produce more of a compound called adenosine triphosphate (ATP), which is a source of energy used and stored at the cellular level. Most of the effects of red light therapy come from your body's mitochondria, which absorb natural red light. In various clinical studies, cytochrome C-oxidase in each mitochondria absorbs red light, resulting in the release of nitric oxide - increasing ATP production and reducing oxidative stress [1]. According to the latest research, this reaction occurring in your body leads to a chain reaction in your cells and triggers a series of effects such as increased cell formation, movement, cell death, and reduced inflammation.
Question : How Does Red Light Relieve Pain ?
LED light therapy has modes to encourage cellular repair for skin and healing for pain relief and inflammation. The LED Therapy Wrap uses 660nm and 850nm LEDs to soothe pain and promote healing. The LED Therapy Wrap around your area of choice and relax for 10-30 minutes while warm red light enters the body, stimulating acupuncture points as well as increasing blood circulation and antioxidant enzyme release.LED light therapy delivers light energy to tissues and cells in a similar way plants absorb light energy from the sun. UV-free, beneficial light rays that energize cells and stimulate the body's natural process to build new proteins and regenerate cells relieve arthritic, muscle and joint pain, reduce inflammation and stiffness and increase blood circulation, healing time, and can even combat mood disorders and improve cognitive function.

🚀 The Science Behind the Glow: From Space to Skincare
Red light therapy may feel like a modern luxury, but its origins are deeply rooted in science and space. First used over a century ago to treat skin conditions, red light therapy gained real momentum in the 1990s—thanks to NASA.
In space, astronauts face slower wound healing and muscle loss due to microgravity. To address this, NASA turned to low-level red light (specifically 635nm and 850nm wavelengths), discovering it could stimulate cellular energy production (ATP), accelerate healing, and reduce inflammation. These findings didn’t just help astronauts—they helped spark a revolution in light-based wellness on Earth.
Today, Hello Face builds on that same science, delivering red light therapy backed by decades of research. Whether you're managing pain, improving skin tone, or supporting healthy aging, you're tapping into a technology once designed for the stars—now made for your home.
STEP 1
Light Energy Emitted as Photons
Hello Face L6 uses advanced red and near-infrared LEDs
to emit gentle, non-ionizing light energy—delivered as photons.
STEP 2
Photons are Absorbed in the Mitochondria
When absorbed by the mitochondria (the energy centers of your cells),
light photons are transformed into ATP—your cell’s main fuel source
for repair, renewal, and healthy function.
STEP 3
How ATP Fuels a Chain Reaction of Healing and Repair
ATP is the molecule that fuels cellular metabolism. Red and near-infrared light
boosts ATP production, activating key biological processes like RNA transcription,
protein synthesis, and natural repair of DNA, cells, and tissues.This therapy also
promotes nitric oxide (NO) release to improve circulation and reduce inflammation,
while balanced reactive oxygen species (ROS) signal cellular defense and repair.
The result is enhanced regeneration—including new blood vessels (angiogenesis),
nerve cells (neurogenesis), and the clearance of damaged tissue (phagocytosis)—
all contributing to faster recovery and healthier skin.
Mitochondria in Action: How Light Sparks Cellular Repair
In phototherapy, photons emitted from red and infrared LEDs safely and non-invasively enter treated tissue as non-ionizing light energy. This energy is absorbed by mitochondria, the powerhouse of living cells, and converted directly into the energy-transport molecule adenosine triphosphate or “ATP” used to power cellular metabolism. In turn, the generated ATP drives RNA transcription and protein synthesis stimulating natural repair mechanisms in DNA, cells, tissue, and organs. The benefits of photobiomodulation, i.e. cellular repair during phototherapy, are many, including the spontaneous catalyst synthesis (such as acetylcholine), normalizing intracellular pH, along with encouraging angiogenesis (new arterial growth), neurogenesis (new nerve growth), and phagocytosis (removal of dead cells and scar tissue). Concurrently, the release of nitric oxide (NO) induces vasodilation, improving tissue oxygenation and combatting inflammation.
🌟 Therapeutic Window Principle in Light Therapy
🔬 What Is the Therapeutic Window?
The therapeutic window refers to the optimal range of light energy (measured in Joules per square centimeter, or J/cm²) that produces beneficial biological effects without causing adverse reactions. This concept is central to photobiomodulation (PBM) and ensures that cells are stimulated—but not overstimulated—by light.
📌 Summary:
Light therapy works best within a precise dose range. Staying within the therapeutic window (typically 5–20 J/cm²) ensures safe, effective stimulation of healing, anti-inflammatory, and regenerative processes.
Finding the Perfect Light Dose
The effectiveness of low-level LED light therapy begins with the right dose—one that safely upregulates mitochondrial ATP levels for cellular repair.
Wavelength
Red light, near-infrared light, blue light, and amber light are among the most clinically studied wavelengths, each proven to deliver targeted therapeutic benefits. Hello Face utilizes all four synergistically, with customized doses tailored to treatment protocols for a wide range of conditions—including aging skin, acne, hair loss, muscle and joint pain, wounds, excess fat, and skin sensitivity.
Distance & Irradiance
Light intensity decreases exponentially with every incremental increase in distance from the source—a phenomenon known as the inverse square law. In low-level light therapy, getting the skin as close as safely possible to the LED source is vital to ensure enough light energy is absorbed.
That’s why Hello Face devices are designed for close contact. This minimizes energy loss and allows us to use a moderate, skin-safe power output while still delivering an effective dose.
⚠️ Too much power at close range can irritate the skin. Too little power—or too much distance—can render treatments ineffective.
Proper power + proper distance = optimal therapeutic effect.
Hello Face devices are ergonomically designed to contour closely to the face or body, ensuring minimal distance between the LEDs and the skin. This close-contact design allows us to use a safe, moderate power output of 40 mW/cm²—powerful enough to deliver an effective therapeutic dose, yet gentle enough for regular use without overheating or overexposure. By staying within the proven therapeutic window of 5–20 J/cm², our devices work in harmony with the biphasic dose response curve, supporting optimal cellular stimulation and regeneration.
Treatment Time
Cells need time to absorb light—and light therapy works by delivering the right amount of energy over time. With a power output of 40 mW/cm², our Hello Face device is optimized to safely deliver an ideal therapeutic dose without overstimulating the skin. Scientific research confirms that trying to shorten treatment time with more intense light does not yield better results. In fact, overexposure in a short period can suppress cellular activity and increase oxidative stress.
At 40 mW/cm², achieving a dose of 15–20 J/cm²—the sweet spot for skin rejuvenation, inflammation reduction, and healing—typically requires 6 to 8 minutes per treatment area. This timing allows mitochondria to efficiently absorb the energy and convert it into ATP, triggering natural repair and regeneration.
To build and maintain results, we recommend using the device 3 to 5 times per week for most skincare goals. For more targeted concerns like acne, inflammation, or pain relief, daily use or up to 6 sessions per week may be beneficial during the initial treatment phase.

How Can Hello Face Help You?
Bringing Professional Light Therapy to the Comfort of Your Home.
Red light therapy for weight loss and body contouring removes fat and reduces inches without invasive surgery, needles, incisions, or downtime. These technologies are all based on modulating a specific type of red light. The modulated red light tricks the mitochondria in the nucleus of the fat cell into creating a transitory pore in the cell membrane, allowing the fatty acids and triglycerides to escape into the interstitial space. The liberated fat cell contents then drain by way of the lymphatic system and are processed by the liver as part of the body’s normal course of detoxification. The pore in the fat cell closes in about 48-72 hours and the liberated contents will be expelled in the patient’s stool and urine over the next few days.
Depression has been linked to blood flow. This means that patients with abnormal blood flow in their frontal cortex are more likely to experience depression than other individuals. When light therapy takes place, red light penetrates the skull and enters the brain. This causes an increase in blood flow which can help alleviate depression and anxiety symptoms. ATP production is also increased in the process. Consequently, this leads to a boost of Serotonin and Dopamine in the body which work to elevate the patient’s mood.
