Blue Light Therapy (Acne Treatment)
Blue light at 417 nanometers helps to clear the skin by destroying the P. Acnes bacteria, which is responsible for most mild to moderate acne.
The P. Acnes bacteria is a harmless bacteria that exists and feeds off of human skin. In some cases, however, the bacteria can spread and grow. This clogs the pores and irritates the skin, which in turn produces the inflammation and redness commonly associated with acne. Blue light activates a specific compound in the waste products of P. Acnes, turning the waste into a toxin that, while harmless to the person, destroys the bacteria and thus the cause of the acne.
