Understanding Red Light Therapy: What It Is and How It Works

Unlike UV light (which can damage DNA and cause cancer), red and near-infrared light does not contain ionizing radiation, making it non-carcinogenic and completely safe when used as directed.

🔍 Myth: Red Light Therapy Can Cause Cancer

This is one of the most common concerns—but it’s not supported by research.

✅ Fact: Red Light Therapy Is Non-Ionizing

Red light wavelengths (typically 630nm–850nm) are non-ionizing, which means they don’t carry enough energy to damage DNA or cells in a way that can lead to cancer.

✅ Fact: Clinical Studies Support Its Safety

Dozens of peer-reviewed studies show that red light therapy does not promote tumor growth—and in some preclinical models, it even appears to inhibit tumor proliferation when used carefully.

The National Cancer Institute confirms that red light therapy is safe for human use in cosmetic and rehabilitative treatments.
