Whether you’re looking to enhance your skin health, reduce pain and inflammation, or boost your overall well-being, red light therapy may offer a promising solution. Read on to discover why this non-invasive, drug-free approach is worth considering for your health and beauty regimen.

What Is Red Light Therapy and How Does It Work?

Red light therapy, also known as photobiomodulation or low-level laser therapy, is a treatment that uses low-wavelength red light to stimulate healing and regeneration within the body. This therapy typically employs light-emitting diodes (LEDs) or low-level lasers to deliver red and near-infrared light to the skin and underlying tissues.The fundamental principle behind red light therapy is that certain wavelengths of light can penetrate the skin and be absorbed by cells, particularly the mitochondria. This process is believed to enhance cellular energy production and stimulate various biological processes. The most commonly used wavelengths in red light therapy are:

• 630-660 nm (red light)
• 810-850 nm (near-infrared light)

These wavelengths have been shown to have the most significant impact on cellular function and tissue repair.
