LED Light Therapy 101: How it Works and Its Benefits for the Skin

LED Light Therapy 101: How it Works and Its Benefits for the Skin

LED light therapy is a treatment that use light-emitting diode lights to improve skincare issues, pain, and inflammation. Diodes are semiconductor devices that allow electricity to flow through and when this electrical current passes, it emits light. LED lights are made up of a series of these diodes, which can be arranged to produce different colors of light. But how does it work, and what is the science behind it?

LED light therapy works by emitting specific wavelengths of light which are absorbed by cells in the body. Different wavelengths of light are absorbed by different cells and can have different effects on the body. 

  •     Red light is absorbed by a chromophore called cytochrome c oxidase, which is found in mitochondria (the energy-producing structures within cells). The light energy is then converted into chemical energy, which stimulates the production of collagen and elastin, helping to improve the appearance of fine lines and wrinkles.
  •     When blue light is absorbed by the skin, it is absorbed by a chromophore called porphyrin, which is found in bacteria that cause acne. The light energy is then converted into chemical energy, which destroys the bacteria and helps to clear up breakouts.
  •     Yellow light therapy works by stimulating the production of new collagen and elastin which helps improve the overall tone and texture of the skin. Additionally, yellow light reduces the appearance of redness and inflammation in sensitive or irritated skin and has also been shown to have a calming effect on the mind, making it a great treatment for overall wellness and stress management.

In addition to these specific skin benefits, LED light therapy has been shown to have several general skin-loving effects. It can improve circulation, reduce inflammation, and boost the production of antioxidants, all of which can contribute to healthier, more radiant skin.

The exact mechanism by which LED light therapy is thought to involve the production of ATP (adenosine triphosphate), the main energy source for cells in the body. When cells absorb light, they produce ATP, which can then be used for various cellular processes. For example, increased ATP production has been shown to stimulate the production of collagen and elastin in the skin, leading to improved skin texture and appearance.

Overall, LED light therapy is a safe, non-invasive treatment that can be used to treat a variety of skin concerns. By targeting specific chromophores with different colors of LED light, it can effectively improve the health and appearance of the skin. So, if you want to rejuvenate your skin, LED light therapy might be a great option for you. While more research is needed to fully understand the mechanisms behind LED light therapy, it has been shown to be effective in a variety of settings and for a variety of health and wellness concerns.
