Benefits of Red LED Light Therapy (RLT)

Before we jump into exploring the benefits of RLT, let’s first understand what it is about and how it came to be.

RLT was first introduced in the 1990s by scientists who used it in space to aid in growing plants. The scientists then discovered the intense light from the red light-emitting diodes (LEDs) played a significant role in promoting growth and photosynthesis in plant cells. The red light was put under further studies to establish whether it could be deployed in the field of medicine; specifically to find out if it could increase the energy in human cells. The researches went on to find out whether RLT could be an effective method to treat slow wounding, muscle atrophy and all bone density issues resulting from weightlessness among space travellers.

So, what is Red Light Therapy (RLT)?

RLT is a therapeutic method that use low-level red wavelengths of light to penetrate beneath the skin surface to eliminate skin conditions such as scars, persistent wounds, and wrinkles.

There are many types of RLT. Photodynamic therapy is a type of RLT that is used along with photosensitising medications. The light from the photodynamic therapy plays the role of an activating agent for the medication. In comparison, RLT found in skin clinics and spas is used to help minimise and eliminate cosmetic skin conditions such as fine lines and wrinkles, inflammation, pigmentation, and stretch marks. Meanwhile, RLT deployed in medical centres is used to treat severe conditions, such as, slow-healing wounds, psoriasis, and side effects from chemotherapy.

Benefits of RLT

Various studies have been conducted by researchers and scientists to establish the benefits of RLT on the general wellness of the body. That means that all the benefits discussed in this article are based on scientific research, studies, and trials.

  1. Skin Health Improvement

Research and studies have proved that RLT is a method that can be deployed to rejuvenate the skin. RLT significantly improves the health of the skin in various ways. First, RLT boosts production of collagen in the skin, which, in return, gives the skin its elasticity. RLT also stimulates blood circulation between blood cells and skin cells, which results in healthy, vibrant, and glowing skin. The light therapy also repairs and strengthens the skin cells to protect them from damage. Lastly, RLT reduces the fine lines on the skin and reduces wrinkle severity to give the skin a perfect complexion and texture.

  1. Acne Elimination

In most cases, acne results from clogged skin pores caused by sebum production when the sebaceous gland is altered by UV and UVB rays from sunlight exposure. On continued exposure to these rays, the skin may develop other skin issues, some of which could be as severe as skin cancer.

According to studies, RLT, either alone or combined with other treatments, such as blue light therapy, is an effective method to treat acne vulgaris. The red light penetrates deep into the skin and compromises sebum production that stops the skin pores from being clogged, while also eliminating inflammation and irritation in the affected area.

  1. Boosts Wound Healing

RLT has been approved as an effective technique that aids in speeding up wound healing. RLT achieves this by stimulating the formation of new blood vessels, eliminating inflammation in the cells, and boosting collagen production in the skin.

  1. Reduced Pain

According to researchers, RLT can be an effective technique to relieve pain in people suffering from certain conditions. A review, from the European Journal of Physical and Rehabilitation Medicine, revealed that RLT significantly reduces pain among adults with various musculoskeletal disorders. This is made possible, as the wavelength of the red light has the ability to penetrate deeper into the skin tissue in comparison to other wavelengths.

The technique is also known to have a unique ability to eliminate other issues and pain below the skin's surface, such as joint pains, and muscle tendon injuries. The technology achieves this by reducing the inflammation, and boosting the development of new blood cells.

  1. Enhance bone recovery

RLT has also been identified as an effective method that helps accelerate bone recovery after undergoing facial bone defects treatment. RLT also aids in reducing pain and inflammation during the treatment process.

  1. Solution for hair loss

Various clinical studies have revealed that RLT is a safe and effective method to treat natural hair loss. According to the clinical studies, individuals who were treated using RLT exhibited a significant increase in hair density, growth, thickness and strength. RLT has proven to be effective in treating baldness among both men and women. The best thing about the RLT method in treating hair loss is that it makes use of safe and concentrated wavelengths of natural light, without any use of chemicals, UV rays, or excess heat that could harm your skin. Light Therapy is preferred over other hair growth methods that involve chemicals.

  1. Reduces the side effects of chemotherapy

Chemotherapy usually comes with its side effects that feature excruciating sores, dryness, redness and burning sensations in the mouth and throat. These side effects are commonly uncomfortable and tormenting.

Research conducted by NASA has established that RLT to reduce these chemotherapy side effects. RLT treatment reduces pain from patients, which reduces the use of painkillers, boosts food intake and raises the morale among cancer patients.

  1. Anti-Aging

Most people want to look young for as long as it is possible. The RLT technology has made this dream a reality. A lot of studies have been conducted to establish RLT’s progress on anti-aging. The studies have determined that those who use the RLT method exhibit improved skin complexion and texture. The treatment protects the existing collagen and boosts new production that improves skin texture, pore size, tone and eliminating fine lines and wrinkles, leaving your skin radiant.

The benefits of RLT treatments are surprising to most. If you are looking for an anti-aging treatment you should definitely give RLT a go. It is recommended to start using RLT in your 20s, as prevention is the best cure for wrinkles. If your skin therapist doesn’t offer RLT, or you prefer an at-home red light therapy device, then give Skin Engineers Anti-Aging device a go.
