Red and infrared light
For skin health and photobiomodulation
The experts we follow agree on this.
Red and infrared light support mitochondrial function and skin resilience.
Who is behind it
Voices including a Princeton-trained molecular biology PhD, a board-certified cardiologist and a GP with a Master of Public Health.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“the red spectrum of light penetrates into the mitochondria kicks nitric oxide off and then the electrons can flow through”
a board-certified cardiologist
Red and infrared light primes skin for UV light assimilation, supports melanin production, reduces inflammation, and stimulates mitochondrial energy production.
Morning red and infrared light preconditions skin to tolerate UV exposure without burning
Red and infrared light directly stimulate mitochondrial electron transport chain to facilitate energy and water production, which artificial indoor lighting lacks
Red and infrared light can help support exclusion zone water hydration around cells.
Red and infrared light at low sun angles penetrate deeply and support energy-hungry tissues like the retina and mitochondria
Preconditioning with red and infrared light helps mitochondria buffer stress from blue light environments.

Entrain shows what the experts teach, so you can make better decisions with your own clinician. It does not diagnose or prescribe. If something is worrying you, start there.
How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Mostly expert experience so far, with published research still catching up.
Some statements come from sponsored segments or people speaking about their own products. They are marked where they appear and count for less. Last refreshed 23 September 2026.
