scientific research

Red light therapy isn't a beauty trend — it's a decades-old field of research called photobiomodulation, and it's the foundation everything we build sits on. Here's the actual science behind the wavelengths in our devices, and how we approach research as a company.

Evidence-Based Light Therapy

Different wavelengths of light do different things at the cellular level. Red light (630–660nm) and near-infrared light (810–850nm) penetrate the skin and stimulate mitochondria to produce more ATP — the energy your cells use to repair themselves and produce collagen. Blue light (450nm) works differently: it targets and destroys acne-causing bacteria on the skin's surface. This is the mechanism behind every Aura Sweden device, not a proprietary claim — it's published, peer-reviewed research, with sources linked below.

What Our Customers Report

Beyond the published research, real usage matters. Customers using Aura Sweden devices consistently report visible improvements in skin tone and texture, fewer breakouts, and better recovery after exercise — you can read verified, named customer testimonials with before-and-after photos on our homepage and individual product pages. These are real customer reports, not a formal clinical trial — we want to be clear about that distinction, since it matters.

Ongoing Research

Photobiomodulation research is still an active, evolving field. We stay current with new published studies as they come out, and we use that research — not guesswork — to decide which wavelengths and specs go into new devices.
