You can't overdo LED light therapy. Overuse won't cause burning or damage to the skin, but it won't fast-track your results either. There are optimal doses of red light therapy depending on the desired result - more doesn't necessarily mean better!

Treatment times of 10-15 minutes per area, at a distance of 6 inches from your device, can be optimal for certain benefits. Beyond that, the evidence suggests diminishing returns as your cells can only absorb so much light at once.

Eye protection provided should always be used when operating the device. Avoid staring directly at the LEDs. If your eyes are sensitive to light or if you take medications that cause photosensitivity, consult a medical professional before use.

Remove makeup, lotions, and serums before red light therapy to allow better penetration of the light. You can use specific red light therapy products if desired, but avoid lotions and creams that may obstruct the light. Moisturize your skin after therapy.

Red light therapy has an immediate effect on the body, so you can expect to experience some benefits right away. For instance, you may notice reduced pain and swelling in an injured area or improvements in mood and sleep quality.

For red light therapy, wavelengths of either 660 or 850 nanometers are optimal. 660 nanometers is more common for skin-related treatments, while 850 nanometers is often used for sports recovery purposes.
