The conclusion at a glance:Light therapy is an effective treatment that can help a wide variety of skin conditions and is backed by a robust body of clinical evidence. While many traditional skin treatments provide temporary relief, these studies have shown real, long-lasting skin changes as a result of light therapy.
Red Light Therapy provides:
The skin is the body's largest organ and collagen is one of its most important components. As you get older, the collagen content decreases by 1% per year (per unit area of skin surface). This decrease can be seen in the form of a wrinkling, loose and sagging skin.
The ever-increasing demand for more beautiful skin is at a new high. In fact, the number of spa visits around the world has passed the 200 million mark per year. And it is estimated that the "beauty and anti-aging" market is worth nearly $ 90 billion. Not much at all, right? It's pretty clear that almost everyone wants more beautiful tighter skin.
But there is more to our skin than just aesthetics. In fact, the skin is your body's largest organ and is incredibly important. It protects your body from external influences, helps regulate the moisture in your body and provides other important functions. But unfortunately, age comes with specific properties, and for our skin too. In addition to natural aging, which is accentuated by external factors, other skin-related problems can occur such as infections, cancer, scarring and other various conditions from acne to psoriasis. 
You will undoubtedly suffer from a skin problem during your life. And as you probably know, skin conditions can be painful, uncomfortable and bad for self-esteem. It is quite common to seek medical treatment that will alleviate the problem. Within traditional medicine, the therapeutic options depend on the type of skin problem you are trying to address. In most cases, to improve skin conditions and signs of aging, a doctor will use a wide variety of topical treatments and procedures, such as microdermabrasion or chemical peels. And just like other health problems, many people with uncomfortable skin problems also turn to natural remedies to find relief. These include essential oils, salt baths, herbal teas, supplements, and masks.
But another alternative option - red and shortwave infrared light therapy - is growing in popularity within the aesthetic field. This treatment has been extensively studied for improving the skin and has become a prominent treatment in dermatology.
Red and near infrared light have an effect on the energy production in all cells of the body and therefore also on the skin. Daily treatments with a Norahlux lamp give your skin an energy boost. The healthy and healing rays stimulate the skin functions, resulting in better blood circulation and more collagen being produced. There is also a better oxygen supply, higher skin moisture and elasticity of the skin, which reduces wrinkles. Your skin will get a younger and fresher look!
Treatments with our Norahlux lamps can also have a healing effect on acne. Because there is a better blood circulation in the skin, the absorption of nutrients and the removal of waste products are stimulated. In addition, the therapy reduces inflammation. By activating collagen, scars can also heal better and more beautifully.
Wrinkles and sagging skin is a normal phenomenon of aging. This is because the body starts to produce less collagen. But external influences also have an effect on the quality and health of our skin.
You may have heard that light damages the skin. This can certainly happen with UV light.
Long-term exposure to the Zon can be harmful to the skin. The photo below is of a truck driver whose left side was always exposed to sunlight. A clear difference from the right side which had that less. That's what excessive sunlight can do.
But a therapy with red and short wave infrared light can actually change your skin in a positive way. Red light made with LED lamps can reverse skin damage caused by UV. 
Research shows that light therapy can improve the appearance of the skin as well as cure the underlying problem causing the condition. When red and short wave infrared light is absorbed through the skin, it stimulates new skin cells to grow healthier, protects against damage and helps heal a number of skin problems.
Not surprisingly, there is a fair amount of clinical research showing specific benefits of light therapy in relation to the skin. An extensive meta-analysis in a 2013 edition of Seminars in Cutaneous Medicine and Surgery evaluated many ways in which light therapy for the skin can be used, some of which are described in the preceding sections. 
As for acne, the same meta-analysis highlighted studies that found red and short-wave infrared light to be effective for treating acne. Importantly, it explains that red light affects sebum production, which contributes to acne, in addition to limiting cytokine, which affects skin inflammation.
Other important studies also showed improvement in treating acne with RLT. [3 - 4]
The meta-analysis also showed that light therapy can resolve psoriasis in patients not helped with traditional treatments, improve pigmentation in patients with vitiligo disorder, and reduce herpes outbreaks. It also enhanced healing and improved burns.
Overall, the authors of the meta-analysis noted that light therapy can be used for many skin problems due to the wide range of positive results. It was particularly effective for healing and skin regeneration, as well as reducing inflammation and cellular necrosis.
This meta-analysis, specifically for anti-aging, has discussed several studies that showed that LED light therapy can reduce and even counteract the signs of aging in the skin. Red and shortwave infrared light have been shown to:
- stimulate collagen
- smooth wrinkles
- improve the tone
- as well as a host of other benefits.
Also notable, while light therapy boosted the skin's positive results, it also reduced an enzyme that contributes to skin damage.
A 2014 controlled study with photobiomodulation and laser surgery also supported the use of red and shortwave infrared light therapy to treat skin aging. The treatment boosted collagen and participants experienced a better look and feel in their skin, which was supported by photos. Overall, researchers found that light therapy is safe and effective. 
In a study with 170 patients, it was concluded that the application of short-wave infrared light to areas with skin inflammation provides significant improvement.
Low-level laser (light) therapy (LLLT) in the skin: stimulating, healing, restorative.
“Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a wide variety of conditions that require stimulation of healing, pain and inflammation relief, and restoration of function. Although skin is naturally more exposed to light than any other organ, it still responds well to red and shortwave infrared wavelengths. The photons are absorbed by mitochondrial chromophores in skin cells. As a result, electron transport, adenosine triphosphate nitric oxide release, blood flow, reactive oxygen species are increased and different signaling pathways are activated. Stem cells can be activated, allowing for tissue repair and healing. In dermatology, LLLT has beneficial effects on wrinkles, acne scars, hypertrophic scars and burn healing. LLLT can reduce UV damage both as a treatment and as a prophylactic measure. In pigment disorders such as vitiligo, LLLT can increase pigmentation by stimulating melanocyte proliferation and decreasing depigmentation by inhibiting autoimmunity. Inflammatory diseases such as psoriasis and acne can also be managed. Its non-invasive nature and almost complete absence of side effects encourage further testing in dermatology. ”

In a meta-analysis on studies on the healing of wounds done with LED and laser in different red and infrared spectrum, it was mainly investigated which intensity is best for the wound healing in question. The conclusion is that relatively low doses of light therapy in the optical window (the spectrum of light to which the body responds best) helps the body to heal wounds more quickly. 
The conclusion of this research is:
The revised studies show that phototherapy, either by LASER or LED, is an effective therapeutic modality to promote skin wound healing. The biological effects promoted by these therapeutic agents are similar and involve the decrease of inflammatory cells, increased fibroblast proliferation, angiogenesis stimulation, granulation tissue formation and increased collagen synthesis. In addition to these effects, the radiation parameters are also comparable between LED and LASER. Importantly, the biological effects depend on such parameters, especially wavelength and dose, emphasizing the importance of determining an appropriate treatment protocol. ”
The consensus is clear:
Numerous clinical studies provide solid evidence that light therapy is an effective skin treatment
A plethora of clinical studies have shown that red and short wave infrared light therapy benefits the skin while reducing potential problems. But it is essential to use the correct wavelengths within the red and shortwave infrared spectrum, along with optimal light intensity. A device such as a NorahLux ensures short and effective treatment times in the comfort of your own home.
