Mike O'Neil, Tria's Director of research explains. Blue Light improves tone, texture, pore size and reduces the tendency of skin to break out. So for overall skin health and appearance, it really is one of the best systems available. Let me show you how Tria technology actually works. Skin is completely covered with tiny hairs. Each hair is in a follicle?also called a pore. Bacteria in the pore can cause inflammation. The Blue Light penetrates the skin and interacts with those bacteria right at the wavelength where they absorb it, which inhibits the bacteria and prevents them from causing inflammation. Just look at the difference in bacteria before and after using the Tria Blue Light. Inflammation really is the thing that we worry about, because it's the root of all evil in skin. So if we address the very heart of the problem first, then we're able to improve the overall health and complexion of the skin. Tria Skin Perfecting Blue Light
