How Red Light Therapy Works

Category: Red Light Therapy

Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, involves the use of specific wavelengths of red light to penetrate the skin and stimulate cellular activity. When the light is absorbed by the mitochondria, which are the powerhouses of the cells, it triggers a series of beneficial reactions. One of the key mechanisms behind red light therapy is the stimulation of collagen production. Collagen is a protein that provides structure and elasticity to the skin. As we age, collagen production naturally declines, leading to wrinkles, sagging, and other signs of aging. Red light therapy helps to reverse this process by activating fibroblast cells, which are responsible for producing collagen. The increased collagen production results in smoother, firmer skin. In addition to collagen production, red light therapy also improves circulation. The light energy stimulates the formation of new capillaries, which enhances blood flow to the treated area. This increased circulation brings more oxygen and nutrients to the cells, promoting faster healing and tissue repair. Furthermore, red light therapy has anti-inflammatory properties. It can suppress the production of pro-inflammatory cytokines, which are molecules that contribute to chronic inflammation. By reducing inflammation, red light therapy can alleviate pain, swelling, and redness associated with various conditions.
