Laser targets the deeper layers of the skin without harming the skin's surface. Laser kills Propionibacterium acnes, or P. acnes, which causes inflammation. They also can reduce the appearance of scars and improve skin texture. Laser therapy is costly and reserved for people who do not respond to traditional acne treatments.

Blue Light Therapy

Blue light therapy is low-intensity blue light used to kill P. acnes. For best results, ongoing treatment is necessary, according to the Mayo Clinic. Blue light therapy can be used in combination with red light therapy. The side effects of blue light are a temporary redness and dryness of the treated skin.

Pulsed Dye Laser

Pulsed dye laser therapy did not show significant improvements in treating facial acne, according to a 2003 study by the Department of Dermatology at the University of Michigan Medical School. A sampling of 40 patients ages 13 and older who were treated with pulsed dye laser therapy from August 2002 through September 2003 did not show any difference between treated and untreated skin.

Red Light

Clinical trials by the Department of Primary Care and Social Medicine at the Imperial College in London showed positive results using red light therapy for treating acne vulgaris. The best results were achieved when red light and blue light therapies were combined. Red-blue light therapy was more effective than topical benzoyl peroxide cream.

Diode Laser Therapy

Diode laser therapy is used to reduce oil production by destroying the sebaceous glands in the middle layer of the skin. This does not harm the outer layer of the skin. This therapy is painful, and topical painkillers are applied to the skin before treatment. There is some temporary redness and swelling after the treatment. A study on acne phototherapy with a 1,450 diode laser in the March 2007 issue of the Doverpress concluded that diode therapy is effective in treating mild to moderate acne lesions. The diode laser used on 25 patients had reduced lesions by 51.7 percent after eight weeks and 63 percent after 10 weeks for 96 percent of the patients.

Green Light Lasers

Green light lasers have been studied as a treatment for acne. Acne lesions decreased and sebum excretion rates decreased, according to the New Zealand Dermatological Society. A study of 11 patients with four treatments over a period of one month showed improvements of decreased acne lesion counts of 35.9 percent and reduced sebum excretion rates of 28.1 percent.
