Also known as low-level laser therapy, Red Light Therapy works by producing a biochemical effect in cells that strengthens the mitochondria (where the cell’s energy is created). With more energy, the cell can function more efficiently, rejuvenate itself, and repair damage; in short, red light promotes healing. Because of its longer wavelength, it is able to penetrate deeper into the skin to help with inflammation and can be more effective with treating targets like the sebaceous glands.
