What is red light therapy and how does it work?

Red light therapy involves the use of specific wavelengths (ranging around 600nm) of red light to promote rejuvenating and provide various therapeutic benefits. Here's how it works:
-
Light Absorption: Red light penetrates the skin and is absorbed by cells in the body. The primary target of red light therapy is the mitochondria, which are the powerhouses of the cells responsible for generating energy.
-
ATP Production: Red light stimulates the mitochondria to produce adenosine triphosphate (ATP), which is the energy currency of cells. This increased ATP production enhances cellular metabolism and promotes tissue repair and regeneration.
-
Increased Blood Circulation: Red light therapy improves blood circulation in the treated area. It causes the blood vessels to dilate (vasodilation), which allows for better oxygen and nutrient delivery to the cells while aiding in the removal of waste products.
-
Collagen Production: Red light therapy can stimulate the production of collagen, a protein that supports the structure and elasticity of the skin. This can lead to improved skin tone, reduced wrinkles, and enhanced wound healing.
-
Activation of Cellular Processes: Red light therapy can influence various cellular processes, including DNA synthesis, protein synthesis, and the release of growth factors. These effects can promote tissue repair, reduce oxidative stress, and support overall cellular function.
Red light therapy is considered safe and non-invasive, and it can be administered using different devices such as LED masks, panels, lasers, or lamps. The therapy can be applied directly to the skin or through the use of light-emitting devices positioned at a distance.
