is red light therapy safe

Red light therapy is generally considered safe when used correctly, especially for short-term treatments. It does not emit harmful ultraviolet (UV) rays, which are known to cause skin cancer, and it does not typically result in permanent skin damage. However, precautions such as protecting the eyes with goggles are recommended, as red light can cause eye damage. Some people may experience side effects like redness, swelling, or blistering of the skin if the light intensity or exposure time is too high. Certain groups, such as those with photosensitive conditions like lupus, porphyria, or on photosensitizing medications, should consult a healthcare provider before using red light therapy. It is also advised to avoid using it on open wounds or infections without medical supervision. The safety profile can also vary based on skin type, with darker skin tones potentially needing adjusted treatment parameters to avoid adverse reactions like blistering. Overall, red light therapy is well tolerated and non-invasive, with rare side effects when properly administered.
