Red and near-infrared light penetrates tissue and is absorbed by mitochondria, specifically by cytochrome c oxidase. This interaction is thought to enhance cellular energy (ATP) production, reduce oxidative stress, and modulate inflammation. For healthspan, improving mitochondrial function at a cellular level may support tissue repair, skin health, joint function, and muscle recovery, counteracting age-related decline in these areas.
Verdict
A safe, targeted tool for skin, joints, and recovery.

Protocol
- Daily 10-20 minute sessions targeting specific body areas with a high-power panel.
- Full-body exposure for 10-15 minutes, 3-5 times per week for systemic effects.
- Use of smaller devices on the face or specific joints for 5-10 minutes daily.
Flags
- Device quality and power output (irradiance) vary significantly between manufacturers.
- Appropriate eye protection is crucial with high-power panels to prevent retinal damage.
- May increase sensitivity to light in individuals taking photosensitizing medications.
- Evidence for systemic, whole-body longevity benefits remains less established than for localized treatments.
