Red light therapy uses low levels of red light to penetrate your skin. When red light reaches your cells, it is absorbed by the mitochondria. This absorption boosts the production of adenosine triphosphate (ATP), which is essential for cellular energy. Increased ATP can lead to improved metabolism and cellular repair. This process is thought to aid in wound healing and pain relief.

Another key effect is the increase in collagen production. Collagen is a protein that helps maintain the structure and strength of your tissues. Higher collagen levels can improve skin elasticity and reduce wrinkles. Additionally, red light therapy enhances blood circulation, delivering more oxygen and nutrients to your cells.
