Light · The Science

Fuel at the cellular level.

Specific wavelengths of light your mitochondria are built to absorb. Non-invasive, and surprisingly well-evidenced.

What it is

Red light therapy (photobiomodulation)

Red and near-infrared light — typically 660nm and 850nm — is absorbed by the mitochondria inside your cells, where it supports the production of cellular energy (ATP). 660nm works at the skin; 850nm penetrates to muscle and joints.

The mechanism

What happens inside the body

Mitochondrial absorption

Light is absorbed by cytochrome c oxidase in the mitochondria, supporting ATP — the body's cellular energy.

660nm — skin

Visible red light stimulates fibroblasts to produce collagen and elastin, supporting tone and texture.

850nm — deep tissue

Near-infrared penetrates to muscle, joints and connective tissue for recovery.

Lower inflammation

Photobiomodulation reduces inflammation and supports circulation.

The evidence

What the research actually shows

660+850nm
The two best-evidenced wavelengths — skin and deep tissue
−55%
Reduction in muscle-damage markers when light is applied before exercise
Collagen ↑
660nm upregulates type I and III collagen
Non-invasive
No needles, no downtime

Red light at 660nm is absorbed in the skin and stimulates fibroblasts to produce collagen; near-infrared at 850nm reaches muscle and connective tissue. Research in Lasers in Medical Science found photobiomodulation applied before exercise reduced muscle-damage markers by up to 55%, and clinical work consistently shows improvements in skin texture and collagen density.

How it's used

Protocols that work

10–20 minutes per area, several sessions a week.

Skin goals favour 660nm; recovery favours 850nm — most panels combine both.

Consistency over weeks is where results show.
