Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Phototherapy treatment of acne vulgaris

    Researchers from Cairo University in Egypt compared pulsed dye laser (PDL), intense pulsed light (IPL), and light-emitting diode (LED) phototherapy.

    First, the details.

    • 45 patients with moderate to severe acne were randomly divided into 3 equal groups.
      • Group 1 was treated with a PDL.
      • Group 2 was treated with IPL.
      • Group 3 was treated with a blue-red combination LED.
    • Treatment was continued until at least 90% clearance of acne was achieved.
    • Patients were evaluated before starting treatment, at 1 month, and after the final treatment.

    And, the results.

    • Patients treated with the PDL achieved at least 90% clearance of their inflammatory lesions after an average of 4 sessions vs 6 sessions with IPL and 10 sessions with LED.
    • Midway through the study, there was at least a 90% percent reduction in acne lesions treated with the PDL compared to 42% and 35% with IPL and the LED, respectively.
    • Minimal mild and usually self-limiting side effects were reported.

    The bottom line?
    The authors concluded that the results support phototherapy as a treatment option for moderate to severe acne, and longer-term studies in more patients are warranted.
