It is recommended that patients undertake light therapy under the supervision of a qualified professional, rather than attempting to self-medicate.
Individuals who are taking photosensitizing drugs should not use light therapy, except as explicitly directed by a doctor.
Individuals with a strong family history of skin cancer should exercise extreme caution when considering phototherapy.
Some types of light cause progressive damage to human skin. This is mediated by genetic damage, collagen damage, as well as destruction of vitamin A and Vitamin C in the skin and free radical generation.
Visible blue light has been suggested to cause DNA breaks, but available studies have not confirmed this; enzymes within the cells are believed to repair the breaks reasonably well.
Consumers should be wary of medical claims about light therapy from manufacturers. In recent years, the Food and Drug Administration has issued several warnings to the manufacturers of light therapy products who claim to offer a medical cure without research to substantiate these claims.
