What the research says

Low-level light therapy (LLLT), is the application of specific wavelengths of light energy to tissue to obtain therapeutic benefits. The absorption of red and near infrared light energy, also known as photobiomodulation (PBM), upregulates cellular ATP (energy) production that produce a number of biostimulatory effects.

A growing body of evidence, supported by thousands of peer-reviewed and published clinical research papers from prestigious institutions around the world, show us that LLLT not only produces efficacious results in clinical trials, but has now gained mainstream acceptance in treating an ever-expanding list of medical conditions.

How It Works

  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 photoreceptors 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.

Frequently Asked Questions

  • Red light improves the health of your scalp and hair root to prevent hair loss, increase follicle size, and regrow hair.

  • Low-level-light therapy or photobiomodulation is based on Light Emitting Diode (LED) technology and is the application of light energy to the body for therapeutic benefits. It promotes a natural photobiochemical reaction similar to the process of plant photosynthesis. The energy delivered by the LEDs has been shown to enhance cellular metabolism, accelerate the repair and replenishment of damaged skin cells, as well as stimulate the production of collagen — the foundation of healthy, smooth skin.

    Research has shown that LED light therapy may help smooth skin texture, improve skin firmness and resilience, increase lymphatic system activity, restore skin’s natural cellular activity, and reduce the appearance of fine lines, wrinkles, and superficial hyperpigmentation. The treatment is for all skin types, and is non-ablative, non-invasive, painless, and requires absolutely no downtime. Patients or clients can return to their normal activity immediately after the treatment.

  • LED Light Therapy is a highly safe and non-invasive treatment, making it suitable for all skin types and ages. Unlike other light-based treatments, it doesn't use UV rays, so there's no risk of burning or skin damage. The light emitted by the LEDs penetrates the skin gently, promoting healing and rejuvenation without any discomfort or downtime.

    This therapy has been extensively studied and used in clinical settings for decades, with a strong track record of safety. Celluma follows the science of safety and efficacy very closely and that is why it has been FDA-cleared for various applications, including skin care, hair restoration, and pain management. The vast majority people experience no side effects, and the treatment is so gentle that it can be used regularly to maintain skin and hair health.

    However, there are some important contraindications to consider:

    • All photo-sensitive drugs are a contraindication for low-level light therapy.
    • Allow 3-5 days before administering light therapy and consult your doctor if you have recently been taking photo-sensitive prescriptions.
    • Do not use if you are on steroidal medication – injections only.
    • Do not use it over a pregnant belly (but you can use it over the face).
    • Do not use if you have a history of epilepsy or seizures.
    • Do not use over any cancer or any known metastasis before getting clearance from your doctor(s).

    In all of the above, or with children under 12, always consult your primary care physician before using Celluma or any light therapy product.

  • It is the measure of the distance between two successive crests of a wave of light energy. Wavelengths of light energy are expressed in nanometers, and are part of the electromagnetic spectrum, which measures the range of all types of electromagetic radiation.

    From radio waves to visible light to infrared light to x-rays, they all are types of electromagetic radiation - expressed in terms of energy, wavelength, or frequency.

    The Electromagetic Spectrum, Nasa.gov, 2013

  • A nanometer is one billionth of a meter and one millionth of a millimeter. It is the most common measurement for visible and infrared light waves of energy.

  • Celluma emits blue 465 nanometer (nm) for acne, red 640 nm for skin conditions and wound healing, and infrared 880 nm for pain and inflammation. Any blue, red, or near-infrared wavelength within an acceptable wavelength range will be capable of achieving similar results.

  • There is no credible research to support the therapeutic value of wavelengths other than blue, red and near infrared. Blue, red and near-infrared wavelengths are supported by thousands of peer-reviewed clinical research studies to have significant therapeutic value when utilized correctly.
