Red Light Therapy: What It Is & Why People Use It

What It Is

Red light therapy, also called photobiomodulation or low-level light therapy, involves exposure to specific wavelengths of red and near-infrared light. These wavelengths, typically between 600 and 900 nanometers, penetrate the skin and are absorbed by cells, particularly in the mitochondria.

Red light therapy devices range from small handheld units to full-body panels. They emit non-thermal light, meaning they do not produce heat in the way that infrared saunas or heat lamps do.

Why It Matters

Red light therapy has been studied for its potential effects on skin health, muscle recovery, inflammation, and cellular energy production. Research suggests it may support collagen production, reduce the appearance of fine lines, and promote tissue repair.

People use red light therapy for a variety of wellness goals, including skincare, post-workout recovery, joint comfort, and general energy support. It's commonly used in clinical settings, spas, and at home.

How It Works (High-Level)

Red and near-infrared light are absorbed by mitochondria, the energy-producing structures in cells. This absorption may stimulate the production of adenosine triphosphate (ATP), which is the primary energy currency of cells.

Increased ATP production is associated with improved cellular function, which may support processes like tissue repair, collagen synthesis, and inflammation modulation. The exact mechanisms are still being studied, but current research suggests red light therapy may influence cellular metabolism in beneficial ways.

How People Commonly Use It

People commonly use red light therapy by sitting or standing in front of a light panel for 10 to 20 minutes per session, several times per week. Some use handheld devices for targeted areas like the face, joints, or muscles.

Red light therapy is often incorporated into skincare routines, post-exercise recovery protocols, or general wellness practices. It's not a replacement for medical treatment, but it may complement existing health and wellness routines.

Safety & Quality Considerations

Red light therapy is generally considered safe when used as directed. It does not emit UV radiation and does not cause burns or skin damage when used at appropriate distances and durations.

Quality varies by device. Key factors include wavelength accuracy, light intensity (measured in milliwatts per square centimeter), and irradiance uniformity. Devices should provide clear specifications and be tested for safety and performance.

As with any wellness tool, individual results vary. Some people report noticeable benefits, while others experience minimal change. Consistency and proper usage are important for those who choose to use red light therapy.
