Frequently Asked Questions about Red Light Therapy

1. How does red light therapy work?

   • Red light therapy uses specific wavelengths of red and near-infrared light, which penetrate the skin and stimulate mitochondria, the energy-producing parts of cells. This boosts ATP (cellular energy) production, enhancing cell function and promoting healing.

2. Is red light therapy safe?

   • Yes, it is generally considered safe when used as directed. Unlike UV light, red light does not cause skin damage or increase the risk of skin cancer. However, eye protection is recommended during treatment.

3. How often should I use red light therapy?

   • This varies depending on the device, individual needs, and treatment goals. Generally, 3–5 times a week is common for most applications, but a healthcare provider can give tailored recommendations.

4. When will I see results?

   • This depends on the condition being treated. Some people report improvements in skin tone and pain relief after a few sessions, while others may need several weeks to see results in hair growth, wound healing, or deeper muscle recovery.

5. Can I use red light therapy at home?

   • Yes, there are many FDA-cleared red light therapy devices available for home use. However, professional-grade devices used in clinics may be more powerful.

6. Are there any side effects?

   • Side effects are rare but can include temporary redness or slight irritation of the skin. Overuse may lead to skin sensitivity, so it’s essential to follow guidelines.

7. Is red light therapy covered by insurance?

   • Generally, it’s not covered by insurance as it’s often considered a cosmetic or alternative therapy. However, some clinics offer affordable packages, and devices for home use are available at various price points.
