Red and red/infrared LED lights use ranges of wavelengths that penetrate the outer layer of the skin, providing the cells with usable energy. This brings about various reactions in the cells including improved healing, the reduction of inflammation and enhanced production of collagen.
It is not an immediate miracle transformation that will occur overnight, but it will provide you with ongoing improvements that you will begin to see in anywhere from 24 hours to 2 months, depending on the condition, its severity, and how regularly the light is used.
Red and near infrared light therapy are exactly the same except for two differences: Red light is visible and near infrared light is invisible. Near infrared light penetrates into the body deeper than red light.
This depends on the condition you are treating and the device you are using. For most conditions, daily use for at least two weeks is recommended, followed by a once- or twice- weekly maintenance regimen.
Yes. Just because you're seeing results, it doesn't mean that your skin cells are finished doing their jobs. It's just that the results of their efforts are starting to become something you can see and/or feel. Keep up the treatments until you reach your goal level of results. Then you can start a weekly maintenance schedule.
When your skin is clear or your fine lines, wrinkles, or scarring have been reduced or even eliminated, it is best that you continue the use of the light once or twice per week as a part of a regular maintenance practice. This will help to make sure that the benefits will continue over the long-term.
