The therapeutic window · Five wavelengths

Not all light is created equal.

Visible light is mostly wasted on therapy. UV damages. Blue disrupts. Only a specific slice of red and near-infrared light actually reaches mitochondria and does useful work there. The AuroraBox platform delivers five of those wavelengths — each with its own penetration depth, target tissue, and decades of published research.

Currently five wavelengths. Additional therapeutic bands in development for the next platform release.

The five · AuroraBox wavelengths

Each wavelength, what it does.

Every wavelength below is part of every current AuroraBox panel. Same platform, five bands working together — each one tuned to a different depth and tissue.

Surface red · visible

The collagen wavelength.

First band absorbed by cytochrome c oxidase. Reaches the upper dermis where fibroblasts live. The wavelength doing most of the work when you see “red light for skin” anywhere online.

Anti-aging & wrinkle depth — RCT evidence for measurable improvement over 8–12 weeks of consistent use.
Surface wound healing & post-procedure recovery — accelerated re-epithelialization.
Inflammatory acne support — pairs well with standard care.

Deep red · visible

The vascular wavelength.

Penetrates slightly deeper than 630 nm. Reaches deeper fibroblasts and microvasculature. Heavily studied for hair follicle activation and the surprising “pre-conditioning” effect against UV damage.

Pairs with 630 nm for complete red-band dermal coverage on the AuroraBox platform.

The brain wavelength.

Second major CCO absorption peak. First of the near-infrared bands. The wavelength cited in the landmark Nature paper on gamma entrainment, and the one most studied for transcranial applications and mood research.

The clinical workhorse.

The wavelength you’ll find in every serious clinic. Reliable depth, well-studied dosing, and the band behind the most striking findings in the PBM literature — including the Hashimoto’s thyroiditis results.
