What is lllt devices?

What is lllt devices?-lllt devices (lllt devices) sometimes known as Low Level Light Therapy or Photobiomodulation (PBM) is a low intensity light therapy. The effect is photochemical not thermal. The light triggers biochemical changes within cells and can be compared to the process of photosynthesis in plants, where the photons are absorbed by cellular photoreceptors and triggers chemical changes.
What is Laser Therapy?-What can you do if you’ve tried every conceivable way to relieve pain? You’ve been treated by anti-inflammatory drugs, cortisone, painkillers, physiotherapy, massage and maybe surgery. Yet the pain continues unabated.

Laser Therapy has been successfully used to treat a broad range of medical conditions, including musculoskeletal problems, arthritis, sports injuries, post-surgical wounds, diabetic ulcers and dermatological conditions.

Low Intensity Laser Therapy uses red and infrared light for the relief of pain, to accelerate healing and decrease inflammation. When the light source is placed against the skin, the photons penetrate several centimetres and get absorbed by the mitochondria, the energy producing part of a cell. This facilitates tissue repair and accelerates wound and tissue healing. The Low Intensity Laser Therapy is non-invasive, non toxic and often provides a treatment alternative for patients that have not responded to other therapies.

What is lllt devices-Laser Therapy, also referred to as lllt devices (lllt devices), cold laser therapy, photobiomodulation, biostimulation, and phototherapy, has been shown in thousands of peer-reviewed publications to increase cellular survival, proliferation and function. lllt devices is able to stimulate and preserve hair follicles in patients with androgenetic alopecia and other hair loss disorders. lllt devices has been used over the past few years in a number of laser devices (combs, caps, hairdryer-like) for treatment of genetic or acquired hair loss.

Mechanism of Action of Laser Therapy

The laser light is absorbed by mitochondria and increases cellular respiration, and induces activation of transcription factors via reactive oxygen species. The question is no longer whether light has biological effects but rather how energy from therapeutic lasers and LEDs works at the cellular and organism levels and what the optimal light parameters are for different uses of these light sources.

One important point that has been demonstrated by multiple studies in cell culture, animal models and in clinical studies is the concept of a biphasic dose response with the total delivered light energy density (fluence). The reason why the technique is termed Low-level is that there exists an optimal dose of light for any particular application, and dose lower than this optimum value, or more significantly, larger than the optimum value will have a diminished therapeutic outcome, or for high doses of light a negative outcome may result.

Delivering Methods

The methods for delivering the therapeutic light are diverse. The field is characterized by a variety of methodologies and uses of various light sources (lasers, LEDs) with different parameters (wavelength, output power, continuous-wave or pulsed operation modes, pulse parameters, polarization state etc). In 2002 MicroLight Corp received 510K FDA clearance for the ML 830-nm diode laser for treatment of carpal tunnel syndrome. There were several controlled trials reporting significant improvement in pain and some improvement in objective outcome measures. Since then several light sources have been approved as equivalent to an infra-red heating lamp for treating a wide-range of musculoskeletal disorders with no supporting clinical studies.

How lllt devices work?

How does lllt devices work?-mitochondriaLow Level Laser Therapy (lllt devices) has a photochemical effect (like photosynthesis in plants). One of the main mechanisms of action occurs in the mitochondria (the cellular power plant inside every cell). The effect depend on the application of the correct wavelength and density of light, delivered to the target tissues for an appropriate period of time (typically between 30 – 60 seconds). Pulses can improve tissue repair and anti-inflammatory effect, analgesia is best achieved with a continuous beam.


The primary effect occurs when light is absorbed in cytochrome c oxidase a protein within the mitochondria.

When cells get stressed (perhaps due to disease, injury or ageing) the mitochondria produces nitric oxide (NO). This competitively displaces oxygen from cytochrome c oxidase consequently reducing ATP (an essential intracellular cellular energy and extracellular signalling molecule) and causing an over production reactive oxygen species (ROS) and leading to oxidative stress. Oxidative stress is well known to lead to inflammation an cell death via the gene transcription factor NF-Kb.

Low Level Laser Therapy (lllt devices) of the correct wavelength and density, dissociates NO allowing oxygen back in, so ATP is restored and oxidative stress reduced. Once normal mitochondrial function is restored by lllt devices then cell metabolism is improves, and the patient gets better more quickly.

How lllt devices Work?-lllt devices—also called low-level or near-infrared laser therapy—uses low-level light energy to treat a wide array of conditions, ranging from sprains, tendinitis, back pain, and arthritis to temporomandibular disorder (chronic jaw pain), carpal tunnel syndrome, diabetic neuropathy, fibromyalgia, and leg ulcers. Used by some physical therapists, physiatrists, chiropractors, and occupational therapists, it is different from conventional “hot” laser surgery. The FDA has cleared more than two dozen cold laser devices, including some sold on the Internet for home use, for the temporary relief of pain, which means only that they are safe, not necessarily that they are effective. The therapy is noninvasive and painless; no serious side effects have been reported.

It’s not clear how lllt devices might work, but it may have anti-inflammatory effects, help repair connective and other tissues, and release pain-relieving endorphins.

Overall, though, it’s hard to draw firm conclusions because many of the studies have been small, short in duration, and not well-controlled. Plus, there are differences in the devices and how the treatment is delivered in terms of dosage, wavelength, duration, where on the body it is applied, and technique. Cold lasers may work for one condition but not another, and only in some people—and their effect may depend on the degree of injury.

Though lllt devices may provide some temporary relief for some types of pain, it may not affect the underlying ailment or be any more effective than other types of heat delivery,in their coverage policies, both Cigna and Aetna note that there’s little or no conclusive evidence that lllt devices is effective for anything. Even in research suggesting some promise for the therapy in treating conditions such as carpal tunnel syndrome, chronic neck or back pain, and diabetic ulcers, the evidence has been limited and conflicting, and it’s hard to know how much any apparent benefit is due to a placebo effect.

Bottom line: If you have tendinitis or other musculoskeletal pain, work with a physical therapist, who may use lllt devices among other treatments. Some health insurance policies cover it when it’s provided by a health-care professional for certain ailments. Whether it adds much to the benefits of traditional physical therapy—ice, heat, exercise, and massage, for example—is unclear. Lastly, don’t count on getting the same benefit from self-treatment as you might from having it done by an experienced, trained professional. Home devices, which can cost hundreds of dollars and are often touted as a cure for nearly everything, may not have the power to do much of anything.

Why lllt devices?

How does lllt devices work And Application range?-lllt devices uses higher-powered Class 4 lasers. In some cases, laser treatments may use lasers similar to what you might find in a laser pointer. This is not a strong enough laser to be therapeutic. And unlike the type of lasers used to remove tattoos and other surgical or dermatological processes that pin pointedly focus on one area, MLS lasers have a wider range that allows them to spread deeply into the tissues of the body.

Combining the two wavelengths in an MLS laser offers the power of pain relief with an anti-inflammatory action. Lasers increase circulation in the treatment area, sending oxygen and blood to the painful region. This increased circulation and blood flow stimulates tissue healing, cell repair, and healthy tissue growth.

lllt devices is indicated primarily for musculoskeletal pain, including:

Muscle strains, sprains, and tears
Arthritis and other degenerating joint conditions
Slipped or bulging discs
Spinal compression
Injuries to the soft tissues
Pre- and post-surgical pain

Other benefits may include things like improved nerve function and immunoregulation.

What is Low Level Laser Therapy For Hairloss?

Where do I begin? Low Level Laser Therapy for hair loss, or “LLLT” for short, has been around for a long time. The first ever mention of low level laser therapy having a positive effect on hair growth was in 1967. A Hungarian scientist named Dr. Endre Mester was using the new laser technology to see if it would cause cancer in mice. I say “new” because lasers were only invented seven years earlier in 1960. During his experiment he shaved some mice so that the laser could better penetrate their skin (this wasn’t a cutting laser) and while he learned that low level laser light doesn’t cause cancer he also noted that the areas where the mice were “hit” with the laser seemed grow more hair. Is this conclusive evidence that low level laser therapy for hair loss works? Of course not, because the mice didn’t have any sort of genetically programmed hair loss, natural or manmade, and they were essentially just normal average mice with their fur shaved off so it kind of doesn’t make sense, unless there is more to the story, but it is the first documented observation of this phenomenon. Personally, I don’t think we can rule out that he was just shooting lasers as these mice like any ten year old kid would as soon as he got his hands on a new laser toy, like kids do with magnifying glasses on sunny days:) This observation was made a full forty years BEFORE the first FDA cleared laser device for hair loss hit the market. This means that the technology behind laser hair restoration systems isn’t anything new and in fact it is quite old in the overall scheme of things, not to mention it is fairly primitive.

What Type of Hair Loss Does LLLT Treat?

LLLT treats androgenetic alopecia, which is more commonly referred to as male or female-pattern baldness. Androgenetic alopecia is a genetic condition and it is the most common cause of hair loss in both men and women. It affects 50% of males over the age of 40, and 75% of females over 65. People with androgenetic alopecia have a gene that makes them more sensitive to the effects of the androgenic hormone—Dihydrotestosterone (DHT). DHT can build-up in the inner roots of the hair follicles and, in genetically-sensitive individuals, the DHT causes the hair follicles to get smaller and smaller. Eventually the follicles become completely dormant and hair growth stops completely.

What LLLT Can and Can’t Do for hair

LLLT is highly effective at treating the weaker, thinner, wispier hair follicles, making the hair markedly thicker, stronger, and healthier. It’s also great at stopping hair loss in its tracks. LLLT only works if there is an active hair follicle however, and it cannot cause hair growth in hair follicles that are already dead (areas on the scalp where there is no hair at all). Trying to use LLLT in these areas is like trying to fertilize a garden that you forgot to plant – it simple won’t work (and no other medication or therapy will either). It is therefore best to start LLLT as earlier as possible, in order to obtain maximum hair restoration benefits. Also, LLLT can be effectively used by both men and women.
