These devices make use of low-level laser therapy, which is serum a painless and non-invasive treatment procedure. Depending on the product that will be used, the process can be performed even at home and in the absence of an intervention from a medical professional. It will provide stimulation to the follicles, allowing it to grow longer and thicker hair. A low-level light therapy device has the ability to produce only five milliwatts. This is a small amount, and hence, it is incapable of producing fraiche heat upon making contact on the skin. This is as against the traditional lasers that are more powerful, and hence, they can easily become hot. According to several studies that have been conducted in the past, a low-level light will be absorbed by the cells.

This explanation relies on the phenomenon of laser speckle, which is peculiar to laser light. The speckle effect is a result of the interference of many waves, having different phases, which add together to give a resultant wave whose amplitude, and therefore intensity, varies randomly. Each point on illuminated tissue acts as a source of secondary spherical waves. The light at any point in the scattered light field is made up of waves that have been scattered from each point on the illuminated surface. If the surface is rough enough to create path-length differences exceeding one wavelength, giving rise to phase changes greater than 2, the amplitude (and hence the intensity) of the resultant light varies randomly. It is proposed that the variation in intensity between speckle spots that are about 1 micron apart can give rise to small but steep temperature gradients within subcellular organelles such as mitochondria without causing photochemistry. These temperature gradients are proposed to cause some unspecified changes in mitochondrial metabolism.
Fluorescence is a luminescence or re-emission of light, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. The wavelengths involved depend on the absorbance curve and Stokes shift of the particular fluorophore. The third pathway that can occur after the absorption of light by a tissue chromophore, represents a number of processes broadly grouped under an umbrella category of photochemistry. Because of the energy of the photons involved, covalent bonds cannot be broken. However, the energy is sufficient for the first excited singlet state to be formed, and this can undergo intersystem crossing to the long-lived triplet state of the chromophore.
The long life of this species allows reactions hoog to occur, such as energy transfer to ground state molecular oxygen (a triplet) to form the reactive species, singlet oxygen. Alternatively the chromophore triplet state may undergo electron transfer (probably reduction) to form the radical anion that can then transfer an electron to oxygen to form superoxide. Electron transfer reactions are highly important in the mitochondrial respiratory chain, where the principal chromophores involved in laser therapy are thought to be situated. A third photochemistry pathway that can occur after the absorption of a red or nir photon is the dissociation of a non-covalently bound ligand from a binding site on a metal containing cofactor in an enzyme. The most likely candidate for this pathway is the binding of nitric oxide to the iron-containing and copper-containing redox centers in unit iv of the mitochondrial respiratory chain, known as cytochrome c oxidase (see below). It should be mentioned that there is another mechanism that has been proposed to account for low level laser effects on tissue.

Therefore, the energy of a "dose" of light depends only on the number of photons and on their wavelength or color (blue photons have more energy than green photons, that have more energy than red, that have more energy than nir, etc). Photons that are delivered into living tissue can either be absorbed or scattered. Scattered photons will eventually be absorbed or will escape from the tissue in the form of diffuse reflection. The photons that are absorbed interact with an organic molecule or chromophore located within the tissue. Because these photons have wavelengths in the red or nir regions of the spectrum, the chromophores that absorb these photons tend to have delocalized electrons in molecular orbitals that can be excited from the ground state to the first excited state by the quantum.
According to the first law of thermodynamics, the energy delivered to the tissue must be conserved, and three possible pathways exist to account for what happens to the delivered light energy when low level laser therapy is delivered into tissue. The commonest pathway that occurs when light is absorbed by living tissue is called internal conversion. This happens when the first excited singlet state of the chromophore undergoes a transition from a higher to a lower electronic state. It is sometimes called "radiationless de-excitation because no photons are emitted. It differs from intersystem crossing in that, while both are radiationless methods of de-excitation, the molecular spin state for internal conversion remains the same, whereas it changes for intersystem crossing. The energy of the electronically excited state is given off to vibrational modes of the molecule, in other words, the excitation energy is transformed into heat. The second pathway that can occur is fluorescence.

In lllt, the question is no longer whether light has biological effects, but rather how energy from therapeutic lasers and leds work at the cellular and organism levels, and what are the optimal light parameters for different uses of these light sources. One important point that has been demonstrated by multiple studies in cell culture 3, animal models 4 and in clinical studies is the concept of a biphasic dose response when the outcome is compared with the total delivered light energy density (fluence). It has been found that there exists an optimal dose of light for any particular application, and doses 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. Evidence suggests that both energy density and power density are key biological parameters for the effectiveness of laser therapy, and they may both operate with thresholds (i.e., a lower and an upper threshold for both parameters between which laser therapy is effective, and outside. The reason why the technique is termed low-level is that the optimum levels of energy density delivered are low when compared to other forms of laser therapy as practiced for ablation, cutting, and thermally coagulating tissue. In general, the power densities used for lllt are lower than those needed to produce heating of tissue,. E., less than 100 mW/cm2, depending on wavelength and tissue type. Physical mechanisms, according to quantum mechanical theory, light energy is composed of photons or discrete packets buikhuid of electromagnetic energy. The energy of an individual photon depends only on the wavelength.

The results of these biochemical and cellular changes in animals and patients include such benefits as increased healing of chronic wounds, improvements in sports injuries and carpal tunnel syndrome, pain reduction in arthritis and neuropathies, and amelioration of damage after heart attacks, stroke, nerve injury. History, in 1967, a few years after the first working laser was invented, Endre mester in Semmelweis University, budapest, hungary wanted to test if laser radiation might cause cancer in mice. He shaved the dorsal hair, divided them into two groups and gave a laser treatment with a low powered ruby laser (694 nm) to one group. They did not get cancer, and to his surprise the hair on the treated group grew back more quickly than the untreated group. This was the first demonstration of "laser biostimulation". Since then, medical treatment with coherent-light sources (lasers) or noncoherent light (light-emitting diodes, leds) has passed through its childhood and adolescence. Currently, low-level laser (or light) therapy (lllt also known as "cold laser "soft laser "biostimulation" or "photobiomodulation" is practiced as part of physical himalayan therapy in many parts of the world. In fact, light therapy is one of the oldest therapeutic methods used by humans (historically as solar therapy by Egyptians, later as uv therapy for which Nils Finsen won the nobel prize in 1904 2). The use of lasers and leds as light sources was the next step in the technological development of light therapy, which is now applied to many thousands of people worldwide each day.
Hamblin, department of Dermatology, harvard Medical School, bar 414. Wellman Center for Photomedicine, massachusetts General Hospital 40 Blossom Street, boston ma 02114 p, the use of low levels of visible or near-infrared (NIR) light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been. Originally thought to be a peculiar property of laser light (soft or cold lasers the subject has now broadened to include photobiomodulation and photobiostimulation using non-coherent light. Despite many reports of positive findings from experiments conducted in vitro, in animal models and in randomized controlled clinical trials, lllt remains controversial. This likely is due to two main premier reasons; firstly, the biochemical mechanisms underlying the positive effects are incompletely understood, and secondly, the complexity of rationally choosing amongst a large number of illumination parameters such as wavelength, fluence, power density, pulse structure and treatment timing has. In particular, a biphasic dose response has been frequently observed where low levels of light have a much better effect than higher levels. This introductory review will cover some of the proposed cellular chromophores responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption peaks in the nir and photoactive porphyrins. Mitochondria are thought to be a likely site for the initial effects of light, leading to increased atp production, modulation of reactive oxygen species, and induction of transcription factors. These effects in turn lead to increased cell proliferation and migration (particularly by fibroblasts modulation in levels of cytokines, growth factors and inflammatory mediators, and increased tissue oxygenation.
