How to Safely Use Red Light Therapy at Home

Red light therapy is growing in popularity for improving skin health, reducing pain, and enhancing recovery. Home devices—especially those using red light therapy 660nm 850nm wavelengths—offer convenient and effective wellness support when used properly. However, it's important to follow safety tips to avoid unnecessary side effects.

1. Take Proper Precautions

If you’re using a red light therapy device at home, always protect your eyes. Never look directly into the light, especially high-intensity models. Use safety goggles and start in a well-lit room to minimize eye strain. Read and follow the instructions carefully to ensure safe and effective results.

2. Double-Check Medications

While red light devices don’t emit harmful UV rays, some medications may increase light sensitivity. If you’re taking antibiotics, acne treatments, or other drugs known to cause photosensitivity, consult your doctor before beginning red light therapy sessions.

3. When and How Often to Use It

Red light therapy is most effective with consistent use. Start with 10-minute sessions once per day, then gradually increase to 15–20 minutes depending on your skin's response. Use it in the morning for an energy boost or before bed to promote relaxation. Daily use is recommended, though 2–3 sessions per day may be beneficial if you're targeting multiple concerns.
