What is Red Light Therapy?

Red light therapy (RLT), also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), uses specific wavelengths of red and near-infrared light to stimulate cellular function.

Unlike UV light, red and near-infrared wavelengths penetrate the skin safely and are absorbed by mitochondria – the energy-producing structures in your cells. This triggers a cascade of biological responses that support recovery, skin health, and overall cellular performance.

How It Works

Red light (630–660nm) works primarily at the skin surface, supporting collagen production, circulation, and skin tone. Near-infrared light (810–850nm+) penetrates deeper into muscle and joint tissue, reducing inflammation and accelerating recovery.

CUVLÉ devices combine multiple clinically studied wavelengths to address both surface and deep tissue simultaneously – without heat, UV exposure, or side effects.

What the Research Shows

Thousands of peer-reviewed studies support red light therapy for a range of applications including muscle recovery, skin rejuvenation, joint health, and cellular energy production. CUVLÉ is built on these evidence-based parameters – not marketing claims.
