You’ve heard of photosynthesis. It’s the process by which plants transform energy from sunlight into sugar (which is then transformed into ATP through cellular respiration) that they use for their day-to-day functioning. Plants can photosynthesize because they have chloroplasts–special organelles that contain a green pigment, chlorophyll, that is sensitive to light in the appropriate way. Humans don’t have chlorophyll or chloroplasts, so they can’t photosynthesize. Right?
Wrong! Well, it’s true that we don’t have chlorophyll or chloroplasts, and so, strictly speaking, can’t photosynthesize. But we are sensitive to light too, and our cells can also get energy from it, in a process known as oxidative phosphorylation. The mitochondria in our cells are equipped with photoreceptors (cytochrome C oxidase enzyme) that capture photons of light, particularly red light. The effect of visible red and near-infrared light on the mitochondria is a cascade of chemical reactions, including the release of oxygen ions and the production of ATP (adenosine triphosphate), the main source of energy of our cells.
This oxidation and energy mobilizes the natural processes of body repair. It revitalizes cells and provides an overall sense of well-being. The skin produces more collagen, elastic fibers, and hyaluronic acid, muscles have more energy to contract and relax, and blood microcirculation increases. More than 4000 scientific studies have been published to date highlighting the effectiveness of red light photobiomodulation, the therapeutic application of non-ionizing, photon energy below the level of thermal damage.
The detailed mechanics of oxidative phosphorylation were only discovered in the 2000s, but people have known about the healing benefits of light since ancient Egypt, and scientists have been studying the topic for the last century. Danish doctor, Niels Finsens, won a Nobel Prize in 1903 for rediscovering the effects of light to treat certain diseases. In the 1960s, NASA researchers discovered that red light awakens cell activity, and they have continued to publish studies showing its stimulating and revitalizing effects on the brain, muscles, joints, bones, and skin. Everyone knows that normal exposure to natural sunlight is beneficial—it regulates the sleep/wake cycle and helps with the synthesis of vitamin D. But the white (multi-colored) light of the sun does not have red light in the intensity necessary to really harness all of its regenerative powers.
The Helight emits red LED light, at exactly the wavelength best picked up by the photoreceptors in our cells. This light acts especially on damaged cells because they have a lower reaction threshold to the effects of light and an easier response to energy transfer. The light from the Helight does not have any harmful UV or InfraRed light, and is very low intensity and does not pose any danger for the body or the retina. The red light allows us to enjoy the beneficial effect that come with a lot of sun exposure, without any of its disadvantages. Helight light is a so-called “cold” light, therefore without heat emission. It is natural and non-invasive, with no side effects and no pain. Furthermore, the exposure to red light is particularly pleasant, relaxing, and soothing.
So, what can the Helight do for me? Helight’s red light can work all kinds of wonders.
By stimulating the production of collagen, elastine, and hyaluronic acid, it can lighten and even skin tone, firm up skin, repair sun or otherwise damaged skin, refine skin texture, tighten pores, increase radiance, fade wrinkles, and fade stretch marks. Use it on your face, neck, hands, or body to tone your silhouette or rejuvenate your skin. Fibroblast stimulation in the scalp can lead to capillary re-densification, which decreases hair loss.
For athletes, the red light can increase cellular oxygenation to produce energy needed for the contraction and relaxation of muscles, increase drainage, increase microcirculation, and increase joint flexibility–all of this helps with athletic recovery.
Red light has also been shown to have several medicinal applications, although this is not what the Helight is recommended for.
Plus, the red light stimulates the production of melatonin, so you can enjoy all of the above benefits while resting, relaxing, and decreasing stress. Come try it out today!
