An emerging method to treat acne includes use of lasers and light therapies. Blue light therapy is the best known of these treatment methods. However, the overall effectiveness of blue light therapy is still inconclusive.
How It Works
Blue light therapy is a procedure approved by the U.S. Food & Drug Administration. The skin is exposed to a narrow-band, high-intensity blue light source which kills the bacteria that causes acne. This painless procedure can also be used to treat inflamed acne that hasn't responded to other therapies. Of all light and laser therapies, blue light therapy is currently the most widely-advertised and used.
Is it for you?
Blue light therapy is appropriate for people with inflammatory acne. However, those with cystic or nodular acne typically do not benefit from this treatment. At least one study conducted on blue light therapy indicated that it made nodular acne worse.
How It's Done
Patients receive several blue light therapy treatments, usually around eight over a period of four weeks. Sessions can be a short as 15 minutes. After treatment, patients may note dryness and swelling, as well as temporary pigment changes in the skin.
What Studies Show
Studies conducted on blue light therapy are limited and the number of clinical participants small. One U.S. study compared use of the topical antimicrobial clindamycin and blue light therapy. Participants noted a 22.25 percent improvement on the side of the face treated with clindamycin, while the side treated with blue light therapy showed 39 percent improvement. However, after eight weeks and no additional blue light treatment, the side of the face treated with clindamycin showed better results. According to the American Academy of Dermatology, around 55 percent of people note improvement with blue light therapy.
How Much Does it Cost?
Blue light therapy is still considered an experimental procedure, so it might not be covered by a health insurance plan. Patients who opt for this treatment can expect to pay between $100 and $200 per session. With multiple sessions required, this can ultimately cost the patient between $800 to $1,600.
