The LYMA Laser uses near-infrared light at 808 nanometers to penetrate deep into the skin, where it is absorbed directly by cellular mitochondria. This process, known as photobiomodulation, triggers biological signalling pathways that upregulate longevity genes, particularly SIRT1. In published clinical research, The LYMA Laser upregulated SIRT1 6-fold, activating genes responsible for cellular repair, DNA protection and collagen production. Unlike traditional lasers that rely on heat or trauma, this cold laser technology energises cells to function younger without causing any damage or inflammatory response.
