Definition of Red Light Therapy

R

Red light therapy is a non-invasive and natural treatment that involves exposing the human skin to red and near-infrared light wavelengths. This type of skin care therapy is also known as low-level laser therapy (LLLT), low-power laser therapy (LPLT), photobiomodulation therapy (PBM), cold laser therapy and soft laser therapy.

The red light therapy devices emit light sources that penetrate deep into the skin cells to improve cellular function, increase blood flow, and reduce oxidative stress. Low-level laser light therapy is gaining popularity due to its numerous potential benefits, including improving the human skin health, promoting hair growth, reducing inflammation, increasing production in wound healing, and even potentially treating certain medical conditions.

Who invented Red Light Therapy?

Red light therapy, also known as low-level laser therapy or photobiomodulation therapy, has been gaining traction in recent years as a potential treatment for a wide range of health conditions. But where did this therapy originate, and who first discovered its benefits?

The origins of red light therapy can be traced back to the research of Hungarian scientist Endre Mester in the 1960s. Mester was studying the effects of low-level laser therapy on tumor cells in mice when he noticed something unexpected: the hair on the mice that had been treated with the laser started to grow back more quickly than on the untreated mice. Intrigued, Mester began to investigate further and found that in addition to stimulating hair growth, the laser therapy also had a surprisingly positive effect on production in wound healing.

Mester’s groundbreaking research laid the groundwork for the development of red light therapy as we know it today. However, it was largely ignored and considered bogus by the medical community for several decades.

It wasn’t until the 1980s that red light therapy began to gain some mainstream recognition. NASA became interested in the therapy as a potential treatment for wound care in astronauts, who were at risk of developing serious infections from even minor injuries in the low-gravity environment of space. NASA conducted numerous studies on the use of red light therapy to treat wounds, and found that it not only accelerated healing times but also showed promise as a treatment for a range of other conditions.

Despite the interest from NASA, red light therapy remained controversial and largely dismissed by many in the medical community. It was only in recent years, as more studies have been conducted and more people have experienced the benefits firsthand, that it has begun to gain wider acceptance.

Today, red light therapy is used for everything from improvements in skin complexion and reducing age spots to treating chronic pain and helping people with seasonal affective disorder (SAD). It is still a relatively new and evolving field, but one that holds a great deal of promise for the future.

Advantages of Red Light Therapy

Red light therapy has been gaining popularity among skincare enthusiasts and healthcare providers for its potential benefits. By using specific wavelengths of light, red light therapy can penetrate deep into the human skin and provide various therapeutic effects.

Although the research on the benefits of red light therapy is not consistent, experts agree that it could help reduce inflammation, promote the formation of new blood vessels, increase collagen production which leads to collagen density increase, boost antioxidants, and reduce cortisol production.

One of the most significant benefits of red light therapy is its ability to reduce inflammation in the body. Red light therapy may target the inflammation at the cellular level by triggering the production of cytokines. Cytokines are signaling proteins that control the immune response in the body, and by modulating their production, red light therapy can suppress inflammation.

Red light therapy can also promote blood vessel formation, which can help improve blood flow and circulation. Better circulation can lead to faster healing, better nutrient delivery, and more efficient waste removal from the cells. Additionally, red light therapy can stimulate collagen production which will lead to collagen increase, which can enhance skin elasticity and reduce the appearance of fine lines and wrinkles.

Moreover, red light therapy can boost antioxidant production, which can help fight oxidative stress in the body. Oxidative stress is a process that occurs when the body produces harmful reactive oxygen species (ROS) that can damage cells and tissues. By increasing antioxidant production, red light therapy can neutralize ROS and protect the cells from damage.

Finally, red light therapy may reduce cortisol production, which is the hormone responsible for the body’s stress response. High cortisol levels can lead to a range of adverse health effects, including weight gain, anxiety, and insomnia. By reducing cortisol production, red light therapy can contribute to stress reduction and better overall mental health.

In conclusion, while the research on red light therapy’s benefits is not definitive, experts agree that it could be an effective therapy to help reduce inflammation, promote blood vessel formation, increase intradermal collagen density which will boast collagen intensity score, increase antioxidants, and reduce cortisol production.

Disadvantages of Red Light Therapy
