Red light therapy uses special LED lamps that emit light in the red and near-infrared range. Here, we'd like to explain the effects of these red light lamps in more detail. The light penetrates deep into your skin and reaches the cells. Unlike sunlight, no harmful UV rays are used that could damage the skin. Instead, only the soothing and safe red and near-infrared light is used.
The light penetrates the skin to a depth of several centimeters. Red light primarily reaches the upper layers of the skin, while infrared light penetrates deeper, also reaching muscles and tissue.
The mitochondria in cells, often called the "powerhouses of the cell," absorb light. The light is absorbed by receptors, the light-sensitive molecules in the mitochondria (especially cytochrome c oxidase). It's as if the mitochondria were tiny solar panels that absorb light and convert it into energy.
This absorption of light leads to an increase in the production of adenosine triphosphate (ATP), the main energy carrier in cells. With more ATP, cells can work more efficiently and perform their functions better. Imagine your cells getting an energy boost, similar to a car being fueled with high-quality fuel – they can work faster and longer without losing performance.
Increased ATP production accelerates cell repair and growth. This means that damaged cells heal faster and new, healthy cells are formed more quickly. It's as if your body activates an internal repair service that replaces damaged parts quickly and effectively.
Another important aspect of red light therapy is the improvement of blood circulation. The light dilates blood vessels and increases blood flow. This means that more oxygen and nutrients reach the cells, promoting healing and regeneration. This increased blood flow can also help remove toxins from the body more quickly.
Red light therapy can reduce inflammation. Inflammation is your body's response to injury or illness and can cause pain and swelling. Using red light reduces the production of pro-inflammatory molecules, which promotes healing and relieves pain.
Another benefit of red light therapy is the stimulation of collagen production. Collagen is a protein that keeps your skin firm and elastic. As we age, collagen production decreases, which can lead to wrinkles and sagging skin. Red light helps stimulate collagen production, resulting in smoother and firmer skin.
