Five pillars of a longevity routine

Where the research is today, in plain language. Each pillar links to the article or tools behind it.

01

Red light

Red and near-infrared light (photobiomodulation) is studied for how it affects cellular energy. Start with the basics.

Recovery

What studies report on red light around exercise and muscle recovery, and how strong that evidence is.

04

Sleep

The research on red light and sleep quality, including where results are still early or mixed.

Skin aging

What is red light therapy?

Red light therapy (RLT) exposes the skin to low-level red and near-infrared light from LEDs or lasers. Unlike UV light, it is not meant to tan the skin. Researchers believe the light is absorbed by mitochondria — mainly by an enzyme called cytochrome c oxidase — nudging cells toward more energy (ATP) production and a calmer inflammatory state.

Hamblin 2017Hamblin 2018

  1. 01

    Absorb

    Red and near-infrared photons are absorbed by mitochondrial cytochrome c oxidase.

  2. 02

    Energise

    Cells respond with increased ATP, a brief burst of signalling molecules and nitric oxide release.

  3. 03

    Respond

    Downstream effects include reduced inflammation and support for tissue repair.

How red light therapy works

Scroll through a one-minute story of what researchers think happens, from the light to your cells. It's simplified, and real effects depend on the device, the dose and the person.

Red light rays stop in the upper layers; near-infrared rays reach deeper. The view zooms into a dermal cell and then into a mitochondrion, which glows and gives off golden sparks representing ATP.

    Two kinds of light

    Most devices combine red light (about 630–660 nm), which you can see, with near-infrared (about 810–850 nm), which you can't. Neither is ultraviolet, so this light isn't meant to tan or burn.

  2. 0:10

    Rays into the skin

    Light passes the outer epidermis into the dermis, home to collagen fibres, hair follicles and small blood vessels. Red light is mostly absorbed in the upper layers. Near-infrared generally travels deeper, toward the fatty hypodermis. Real depth depends on the device, the dose and the body area.

  3. 0:20

    Zooming into a cell

    Absorbed light reaches cells such as fibroblasts, the collagen-making cells of the dermis. Inside each cell are dozens of mitochondria, often called the cell's power plants.

  4. 0:30

    A mitochondrion lights up

    Research suggests a key light absorber is cytochrome c oxidase, an enzyme on the mitochondrion's folded inner membrane.

    Hamblin 2018Hamblin 2017

  5. 0:40

    Sparks of energy

    In laboratory studies, the right dose of light is linked to more ATP, the cell's energy currency, plus brief signals such as nitric oxide. More is not better: too much light can blunt the effect.

  6. 0:50

    Blood flow

    Nitric oxide helps small blood vessels relax, so light may support local circulation. Human evidence here is still limited.

  7. 0:55

    What it may support

    Clinical trials with specific protocols suggest red light may support:

    SkinResearch suggests it may help soften fine lines and support collagen and skin texture.Read the evidence →
    RecoveryStudies suggest it may support muscle performance and recovery, especially when used before exercise.Read the evidence →
    ComfortTrials suggest it may ease some types of pain, such as neck pain and knee osteoarthritis.Read the evidence →

    The fine print

    Results vary from person to person and build gradually with regular use. Red light therapy is not a cure for any disease and doesn't replace medical care. If you have a health condition, talk to a clinician first.

How a session works

General steps only. Always follow your device's manual. If you are pregnant, photosensitive, taking photosensitizing medication or have an eye or skin condition, talk to a doctor before using light therapy.

Ways to use it

At home or in a treatment room

Red light devices come in many shapes: face masks and handhelds, mats and standing panels for home, and larger overhead systems used in studios and clinics.

Use at home

A mat, a standing panel or a face mask fits into an everyday routine, like a short session while you stretch or relax. Follow the timing and distance in the manual.

In a studio or clinic

Overhead panels, treatment chairs and full-length beds cover large areas at once. They're usually run by trained staff.
