The Science Of Light

POLY - The Science of Light

Since our beginning as UVBioTek, selling narrowband UV-B devices for psoriasis, eczema, and vitiligo, we have maintained a deep passion for providing people with safe, natural, reliable options for taking control of their health and appearance.

In 2016 we began our “Science of Light” project which was designed to leverage the inherent healing properties in light and find new and exciting ways to deliver new treatment options to the aesthetic and wellness marketplaces.

This project has evolved to become the POLY project, which is now culminating in 2017 with the launch of our POLY system – and eventually our entire POLY product line. We are continuing our efforts to develop new systems to treat and manage a wide variety of conditions and hope you’ll be there with us on this exciting journey. In the meantime, please read on see exactly how the science of light is currently working to change people’s lives.

Red Light

Red light at 633 nanometers has a long enough wavelength to penetrate the epidermis (outermost layer of the skin) and reach the dermis (the middle layer of the skin). This enables it to reach fibroblasts, special types of cells that sit beneath the skin and manufacture collagen – a protein that helps tighten and firm the skin and heal wounds.

Red light does this by acting on the mitochondria inside fibroblasts. Mitochondria are small organelles that exist inside most of the cells in your body. They produce the cell’s energy by absorbing oxygen and other materials, as well as by producing a molecule called ATP.

Exposing the mitochondria to red light at 633nm causes a number of changes in mitochondria, particularly, it increases the mitochondrial membrane potential, allowing the mitochondria to receive signals faster. Red light also causes an increase in the production of ATP.

Mitochondria produce ATP by a process called the “electron transport chain.” One enzyme involved in that process is ‘cytochrome c oxidase.’ Cytochrome c oxidase is also a “chromophore”; i.e, a moledule that responds to the presence of light.

Since cytochrome c oxidase is a necessary part in making cellular energy, and since it is stimulated by the presence of red light at 633nm, it will respond by increasing the production of cellular energy. This increases the activity of the cells themselves, and therefore causes the fibroblasts in the skin to produce more collagen to firm, tighten, and improve the overall appearance of the treated area. 

Infrared Light

Infrared light at 850nm acts similarly on the cells as red light. Because the infrared waves are longer, however, they are capable of penetrating through the skin and reaching the inner tissues of the body.

Infrared lights are invisible to the human eye and is primarily felt as heat. As such, it is capable of warming and increasing the blood flow to areas inside the body, which in turn decreases the time to heal internal injury and reduces inflammation from strennous workouts or conditions like arthritis that cause pain and soreness.

Blue Light

Blue light at 415 nanometers works to improve the presence of mild-to-moderate acne by destroying the bacteria on the face and in the pores responsible for causing acne.

The P. Acnes bacteria is a harmless bacteria that exists and feeds off of human skin. In some cases, however, the bacteria can spread and grow. This clogs the pores and irritates the skin, which in turn produces the inflammation and redness commonly associated with acne.

Blue light activates a specific compound in the waste products of P. Acnes, turning the waste into a toxin that, while harmless to the person, destroys the bacteria and thus the cause of the acne.
