LED Light Therapy Colors And Benefits

LED Light Therapy Colors And Benefits

In recent years, LED light therapy has emerged as a revolutionary approach to addressing a wide range of health concerns, from skin rejuvenation to pain management. Among the various options available, red light and blue light have taken center stage, demonstrating remarkable effectiveness in treating various conditions, including skin issues like acne and psoriasis, and even reducing inflammation and pain. 

However, the therapeutic potential of LED light therapy goes beyond just these two colors. A diverse spectrum of hues holds great promise in unlocking new dimensions of healing, offering the potential to alleviate pain, boost the immune system, and enhance overall well-being. Many studies are still being done to better understand LED light therapy's full range of benefits. Thus far, research shows many positive impacts, with the results for different colors still being discovered.

LED Light Therapy

LED light therapy, and the various colors that make up different types within that, fall under the category of photobiomodulation (PBM) therapy. PBM therapy is a light therapy technique that harnesses non-ionizing light sources, such as LASERS, LEDs, and broadband light, operating in the visible and near-infrared spectrum. This non-thermal process involves activating endogenous chromophores, leading to photophysical and photochemical events at different biological levels. PBM devices have received FDA clearance through the Premarket Notification/510(k) process as adjunctive devices for providing temporary relief from pain. These clearances were granted based on the presentation of clinical data supporting such claims' efficacy.

LED (light-emitting diode) light therapy is a non-invasive and effective treatment that works within the layers of the skin to enhance its condition. In the 1990s, NASA initiated research on the effects of LED therapy to promote wound healing in astronauts, facilitating cellular and tissue growth.

Today, dermatologists and estheticians widely employ LED light therapy to address various skin issues. Often used in conjunction with creams, ointments, and facials, LED light therapy synergizes with other treatments to deliver optimal results.

For convenience, a variety of at-home devices utilizing LED light therapy are available. Each device offers different wavelengths corresponding to visible colors. These colors penetrate the skin at various depths, providing unique benefits.

LED Light Therapy Colors

LED light therapy harnesses diverse wavelengths, each associated with distinct visible colors. As these colors are applied, they penetrate the skin at varying depths. Depending on the desired outcomes, treatments can involve the use of individual colors or combinations thereof. This can allow for a more tailed therapy and offer a range of results depending on the colors used.

Red Light

Red light therapy is believed to have an impact on the mitochondria, often referred to as the "power plants" of the body's cells. By providing cells with increased energy, other cellular functions become more efficient, contributing to skin repair, promoting new cell growth, and enhancing skin rejuvenation. Specific cells absorb light wavelengths and are stimulated to function optimally.

In terms of skin health, red light therapy may:

  • Stimulate collagen production, which imparts structure, strength, and elasticity to the skin.
  • Boost fibroblast production, responsible for collagen synthesis and vital for building healthy skin.
  • Enhance blood circulation to the tissue, promoting overall skin health.
  • Reduce inflammation in cells, leading to a calmer complexion.
  • Red light therapy is advocated as a treatment for various common skin conditions, such as improving wound healing, reducing wrinkles and fine lines, and addressing psoriasis, rosacea, eczema, sun damage, scars, acne, and more.

Though red light therapy is an emerging treatment gaining increasing interest, more research is required to fully understand its potential benefits. Notably, this therapy is non-toxic, non-invasive, and gentler than some topical skin treatments. Unlike ultraviolet (UV) light from the sun or tanning booths, which can cause cancer, red light therapy does not employ such harmful light.

If you decide to use a red light therapy device for skin or other health concerns, ensure you protect your eyes, follow all instructions diligently, and maintain proper care of the device. Embracing red light therapy with precautionary measures can pave the way for potential skin improvements and overall well-being.

Blue Light

Blue light therapy is one of the other most common treatments within LED light therapy. It utilizes light to address specific skin conditions either on or just below the skin surface, providing a pain-free procedure. When combined with photosynthesizing drugs, blue light therapy transforms into photodynamic therapy, employing a natural violet or blue light source. This approach is considered an alternative treatment.

Blue light therapy effectively targets areas accessible to light, making it suitable for conditions present on or near the skin's surface. Common applications include treating sun damage and various skin cancer growths, including precancerous and non-metastasized cancerous lesions.

Photodynamic therapy induces a reaction between the applied photosynthesizing drug and oxygen for skin cancer treatment, leading to cancer cell elimination. Additionally, it may trigger immune system defenses or damage blood vessels feeding cancer cells.

Beyond skin conditions and cancer, blue light therapy has been beneficial for various skin disorders. It can improve skin texture, reduce sebaceous hyperplasia (enlarged oil glands), eliminate sunspots, combat acne, and fade acne-induced scars.

Furthermore, blue light therapy demonstrates promise as a treatment for depression, particularly in cases of major depressive disorder with seasonal patterns (formerly known as seasonal affective disorder or SAD). By leveraging light, this therapy can effectively counter the effects of gloomy winter weather, darker days, and increased indoor time, offering relief and improving mood.

Green Light

Recent studies have shown promising results in using green light therapy to alleviate pain and reduce the frequency of migraines, fibromyalgia episodes, and chronic musculoskeletal pain. Whether through exposure to green LED light strips in a dark room or wearing green-tinted glasses, individuals have experienced relief from pain severity and the anxiety often associated with chronic pain.

The precise reasons behind the green light's effectiveness in these conditions are still under investigation, but researchers have proposed intriguing theories. It appears that specific frequencies of green light may activate melanopsin, a light-sensitive neurotransmitter present in the eye responsible for regulating pupil dilation and contraction. 

This interaction with melanopsin may involve the periaqueductal gray matter, a brainstem structure crucial in processing pain. The activation of inhibitory pathways through melanopsin could potentially lead to pain suppression rather than processing, offering valuable pain relief for those experiencing chronic discomfort. As the exploration of green light therapy continues, a deeper understanding of its therapeutic mechanisms is anticipated.

Amber (Yellow) Light

Amber light therapy, also known as yellow light therapy, is a gentle yet powerful non-invasive skin treatment that utilizes LEDs to target the skin cells at a depth of 0.5mm to 2mm. This specific therapy involves exposing the skin to a precise wavelength of around 590 nanometers, giving it a warm yellow-to-orangeish hue.

The benefits of amber light lie in its ability to penetrate the skin, triggering essential cellular responses that promote skin health. Unlike some deeper-penetrating LED lights, amber light therapy is well-suited for addressing a wide range of medical skin issues due to its shallower penetration.

Once absorbed by various skin cells, amber light therapy sets key mechanisms that optimize the skin's metabolic pathways in motion. It interacts with the epidermal cells, encouraging cell renewal and supporting the maintenance of the skin's outermost layer.

Moreover, this specific wavelength has the incredible capacity to activate the lymphatic system, promoting the elimination of toxins from the body. Additionally, amber light therapy stimulates blood circulation, enhancing the skin's ability to retain moisture and maintain hydration levels for a plump and rejuvenated appearance.

Just like other LED light therapies, amber LED light therapy stimulates collagen production, a fundamental process that aids in skin repair, filling in scars, fine lines, and refining skin texture. The result is firmer, more elastic skin, showcasing the remarkable potential of amber light therapy in enhancing overall skin appearance and health. Embrace the soothing radiance of amber light and unlock your skin's natural beauty with this cutting-edge and gentle therapy.

Different Colors And Capabilities

With such a wide range of benefits, it makes sense that people are more interested in LED light therapy as a new treatment option. While more studies must be done to fully understand the benefits and treatment scope, the range of colors boasts an impressive array of potential. Red and blue light therapies are the most studied and utilized in a variety of settings, including at-home devices. These can offer people more flexible, efficient, and adaptable ways to receive treatment.

When looking for at-home devices to use, remember that the color of light needed will depend on what you are looking to treat. Always follow the safety protocols recommended by the seller, your dermatologist, or another healthcare professional. If you are unclear about how to use certain devices, use caution and follow all instructions to prevent misuse.
