Light therapy has an impact on human tissue that behaves similarly to the way that a plant utilizes chlorophyll to convert sunlight into plant matter. By shining LEDs that utilize specific wavelengths of light onto the body, a natural cellular stimulation occurs. The cells absorb the particles of light and transform the energy from that light into a form of cellular energy called adenosine triphosphate (ATP). This basically recharges your cells, which is used to power the metabolic process that synthesizes and utilizes DNA, RNA, enzymes, proteins, and other cellular components.
The body uses these components to repair and regenerate your cells, enhancing cellular performance. That results in increased circulation, improved tissue repair, decreased inflammation, improved skin texture, tone, and clarity, and it can ease muscle and joint pain, stiffness, spasms, and arthritis. It can also kill the bacteria that cause acne vulgaris and decrease fine lines and wrinkles. Other types of light therapy are used to treat mood and sleep disorders, such as circadian rhythm disregulation or seasonal affective disorder. The type and spectrum of light used will determine the appropriate clinical and cosmetic applications.
