What Outside Studies Say About Red Light

Laperlaa does not carry out its own research. The studies below were run by independent scientists, not by us, and they did not test Laperlaa products. We share them for general interest only.

What is red light therapy?

In scientific papers, red light therapy is called photobiomodulation (PBM). It uses low-power red and near-infrared light that does not heat or burn the skin.¹

It is not ultraviolet light and it is not a tanning lamp. Published studies generally use wavelengths of roughly 600–1100 nm.²

UV Visible Red
630–670 nm 700–780
rarely used Near-infrared
800–900 nm

Red light is mostly absorbed near the surface of the skin.¹

Near-infrared light travels a little deeper.¹

How researchers think it works

Independent researchers believe the light is absorbed by the mitochondria, the parts of a cell that produce energy. The exact mechanism is still being studied and is not fully understood.³

A few independent studies

These are external studies by other researchers. They used their own devices and settings, and their results do not tell you how any Laperlaa product will work for you.

Skin

136

adults in an independent trial

Researchers reported that regular red light sessions may help skin look smoother. Results varied between people.

After exercise

Review

of trials by outside researchers

Researchers reported that light used around exercise may help with how tired muscles feel. Study quality varied.

What we can and can't say

We don't guarantee any result. At most, red light may help as one part of a self-care routine, and experiences differ from person to person.

Using it safely

Follow your user guide for session length and distance.
Protect your eyes. Don't look directly into bright LEDs.
Check with your doctor first if you are pregnant, have a medical condition, or take medicines that make you sensitive to light.
