What IS LED LIGHT THERAPY?

Light emitting diode (LED) therapy, also known as photobiomodulation or low-level light therapy (LLLT), is the application of specific wavelengths of light energy to tissue to achieve therapeutic benefits. This non-invasive treatment is effective for addressing various conditions, including acne, aging skin, pain, hair restoration, excess fat, and more. The absorbed light energy enhances cellular performance, promoting self-repair and rejuvenation—just as nature intended.

Phototherapy, particularly LED red light therapy, is well-researched and supported by thousands of peer-reviewed clinical studies from prestigious institutions worldwide. This clinically validated technique is increasingly recognized by dermatologists, cosmetic and general surgeons, and pain management professionals globally, gaining widespread acceptance in mainstream medicine.

Light Therapy In Practice

Light therapy can be delivered through light emitting diode (LEDs) devices or cold LASERs, and has a variety of applications across many medical fields. Over the last decade, different applications of light therapy have gained mainstream attention and prevalent use in both clinical and at-home treatment.

Phototherapy, or light emitting diode (LED) red light therapy, has been widely researched and is supported by thousands of peer-reviewed and published clinical research papers from prestigious institutions around the world. Other terms by which light therapy is referred to are photobiostimulation, photobiomodulation, photomedicine, LED light therapy, low-level light therapy (LLLT), red light therapy, blue light therapy, cold and soft LASER therapy. All terms are correct, have the same meaning and are used to describe the delivery of light energy to treat a variety of medical and cosmetic conditions.

How It Works

  • Celluma Step 1 Celluma Step 1
  • Celluma Step 2 Celluma Step 2
  • Celluma Step 3 Celluma Step 3
  1. STEP 1

    Light Energy Emitted As Photons

    Light therapy works by emitting particles of light (photons) at specific wavelengths like red and near infrared light.

  2. STEP 2

    Photons are absorbed in the mitochondria

    In our cells, light energy is absorbed by photoacceptors in the mitochondria.

  3. STEP 3

    Increased ATP causes a cascade of metabolic events

    The resulting elevation of ATP (adenosine triphosphate), or cellular energy, is used to power metabolic processes to repair or regenerate cell components and foster mitosis, cell proliferation, and restore homeostasis.

The Mighty Mitochondria

Boosting Cellular Energy With LED Light Therapy

Research indicates that the mitochondria in our cells absorb particles of light (photons) and transform light energy into adenosine triphosphate (ATP), the form of energy that cells utilize. The resulting elevation of ATP is then used to power metabolic processes, synthesize DNA & RNA proteins, enzymes, and other products needed to repair or regenerate cell components. It also fosters mitosis, or cell proliferation, and restores homeostasis. Simply put, LED light therapy provides compromised cells with increased energy so cellular performance, repair, and rejuvenation is enhanced naturally.

Getting Just The Right Dose

We know that effective results from low level LED light therapy starts with the factors that provide a safe, effective dose that up-regulates mitochondrial ATP levels.

Proven Wavelengths

Red light, near infrared light, and blue light are the most clinically studied and proven to produce beneficial effects. Celluma utilizes all three wavelengths synergistically, with doses dependent upon the type of treatment protocol for conditions like aging skin, acne, hair loss, muscle and joint pain, wounds, and excess fat.

Distance & Power

Power and distance from the light source are directly related. In low-level light therapy, like in photography, the inverse square law tells us that with each incremental increase in the distance from the light source, there is an exponential decline in the intensity of light. So ensuring the proper distance from a light source that utilizes a proper power output is an important balancing act in ensuring both safety and efficacy. Too much power at a close distance can be toxic and harmful to the skin. Too little power (or too much distance from the LED source), and treatments will be ineffective.

Celluma devices are designed to be flexible and shaped around the face or body, as close to the skin as possible. Therefore, we are able to make devices that require less power, are safe to have close to or directly on the skin, and most importantly deliver an effective dose within the biphasic dose response curve within 2 - 10 Joules/cm2

TIME

Cells need time to absorb light. You can't speed up nature (or results) if you don't give your body enough time to absorb the light energy that stimulates the up-regulation of mitochondrial ATP levels. There is a lot of misinformation claiming that more powerful devices will deliver the same results in less time. This is not supported by the scientific research, and could also lead to harmful effects. As long as the optimal dose is delivered safely and correctly with the right power output, distance, and proven wavelengths, 30 minutes will get you the optimal results.

Patented Shape-Taking Design

The distance between the light source and treatment area is critical for successful outcomes.


Human bodies are not flat. Thus, maintaining a consistent proximity between the body and the light source is crucial in delivering the optimal dose of light energy to our cells. Which is why we designed and patented our award-winning, flexible, shape-taking technology that allows anyone to contour Celluma LED panels as close as possible to the skin for getting just the right dose of uniform light energy for safe, effective results.

The Science of LED Light Therapy and the Skin

When it comes to aging, a significant factor that leads to wrinkles, fine lines, and joint pain is due to inadequate collagen levels. Collagen is the main structural protein found in your skin and other connective tissue. Collagen literally holds our bodies together. An easy way to remember what collagen does is to look at the Greek prefix ‘kolla’ which means glue.

Increased fibroblast proliferation is just one benefit of LED red light therapy. Fibroblasts make collagen fibers, so it stands to reason that the more, and healthier, fibroblasts we have in the skin, the more and better collagen fibers are made. And as we all know, collagen synthesis and maintenance is the bedrock of anti-aging. Collagen is a key to longevity.

Healthy collagen levels are what give us a glowing complexion, firm skin, strong nails, dense bones, and healthy hair. It is also essential in keeping muscles, joints, and tendons in healthy working order. Simply put, the more our bodies produce collagen, the better we’ll look and feel as we age and attempt to delay tissue and cell degeneration.
