LED light therapy (especially blue, red, purple, and yellow) has been shown to be effective for a variety of skin conditions, anti-aging, healing, and pain relief with proper and regular use. Even though it does not share the same wavelengths of light with UV rays that are known to fade tattoo color, the long term effect of red light therapy on tattoos is not yet fully known. Therefore it would be better to err on the safe side and protect any important tattoos, such as delicately tattooed eyebrows, from any unwanted effects. Covering your tattoo to keep it safe from light treatments can be as simple as using a piece of white fabric that is taped or rested in place.
