Red light therapy (RLT) has become one of the most popular biohacking tools, backed by hundreds of clinical studies showing benefits for skin health, muscle recovery, joint pain, and more.
What is Red Light Therapy?
Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), uses specific wavelengths of red (630-660nm) and near-infrared (810-850nm) light to stimulate cellular function.
The light penetrates the skin and is absorbed by mitochondria, boosting ATP (cellular energy) production. This leads to:
- Improved skin health — Reduced wrinkles, acne, and scarring
- Faster wound healing — Stimulates tissue repair
- Reduced inflammation — Decreases inflammatory markers
- Pain relief — Effective for joint pain, arthritis, and muscle soreness
- Better sleep — Supports circadian rhythm when used in the morning
How to Choose a Red Light Therapy Device
Key factors to consider:
- Wavelength — Look for 660nm (red) and 850nm (near-infrared) dual wavelength
- Power density — Higher irradiance (100+ mW/cm² at 6 inches) means shorter treatment times
- Coverage area — Panels for full body, masks for face, belts for targeted areas
- EMF levels — Low EMF is important for daily use
- Price per watt — Compare value across devices

- Near-Infrared (850nm): Penetrates deeper — muscles, joints, bones
- Best option: Devices with both wavelengths for full-spectrum benefits
Frequently Asked Questions
How long until I see results?
Most people notice improvements in 2-4 weeks of consistent use. Skin improvements may be visible in as little as 1-2 weeks.
Is red light therapy safe?
Yes, red light therapy has an excellent safety profile. It doesn’t use UV light and doesn’t burn the skin. Thousands of studies support its safety.
