This is an alternative therapy that is aimed for those who suffer from acne but have had little success in treating it. This therapy focuses on killing off the bacteria that causes acne formation. This bacterium is called propionibacterium acnes or P. acnes. P. acnes causes small molecules to produce bacteria that causes most types of acne. These molecules are known as porphyrins and blue light therapy works to zero in on the porphyrins. When these molecules are exposed to blue light, they produce free radicals that destroy the bacteria.
This treatment is becoming very popular because it is both non-invasive and drug free. Many medications contain chemicals that cause damage to the skin. This therapy does not cause this and it is FDA approved and safe for the skin. Blue light therapy is administered in increments. A patient is put on a schedule for several short 15-minute sessions over a period of about 4 weeks.
