What is the primary effect of using LED therapy with red light?

The primary effect of using LED therapy with red light revolves around enhancing collagen production. Red light therapy, also known as low-level laser therapy, stimulates the fibroblasts in the skin. These fibroblasts are crucial cells responsible for producing collagen, a protein that provides structure and elasticity to the skin. As collagen levels increase, the skin appears firmer, more youthful, and better able to heal, which is particularly beneficial in cosmetic treatments for anti-aging and skin rejuvenation.

While LED therapy can also have beneficial effects such as reducing inflammation and softening scars, these are secondary outcomes rather than the main purpose of red light therapy. The enhancement of collagen production is a clearer and more direct goal pursued through the use of this specific wavelength of light.
