science behind led, red and nearinfrared light

We have gathered some of the science and evidence behind the benefits of our different light therapy treatments. Get the key take-aways in the summary below – or deep dive into the clinical studies and articles documenting the effect of LED, Red and Near-Infrared light therapy.

If confused – below a short explanation of the different types of light:

  • LED light – LED light acts on cells in the skin known as fibroblasts, which play a role in production of collagen, a protein that makes up a large part of connective tissue and helps the skin to recover when it’s harmed, the red color works deep below the surface of your skin to help soothe and repair tissue, and the blue for killing bacteria, both boosting collagen.
  • Red light – Delivered at 660 nm, red light is easily absorbed by surface tissues and cells, leading to improved skin health and healing.
  • Near-Infrared Light – Delivered at 850 nm, near infrared (NIR) light is invisible to the human eye and penetrates deeper tissues, leading to improved recovery and support of inflammation in the body.
  • Photobiomodulation – a combination of red and near infrared light – PBM
  • Therapy, previously known as Low Level Laser Therapy, is the application of red and near-infrared light to tissue where there is degeneration or injury to improve, repair, and reduce inflammation and pain.

Skin health & anti-aging effects

One of the most well known effects of LED light is the improvement of the overall skin structure and the high increase of collagen in the deeper skin layers. Furthermore, LED light is effective in repairing sun damage and reducing wrinkles if used consistently.

Compared to regular facials like peelings and dermatude, that primarily work on the outer layers, the LED light works from the inside out. It does, however, require a continuous build-up and consistency for the full effect, as the skin regenerates at a cellular level – receiving intense cellular energy and enhanced collagen production through the LED light.
