Intense pulsed light
Intense pulsed light
The intense pulsed light (IPL) device generates a strong, polychromatic, and noncoherent light. IPL is used in acne treatment for the photochemical effect of the blue and red light range and the photothermal effect of the infrared light range on porphyrins and inflammatory cells, in addition to heating the sebaceous glands.36 In a split-face controlled clinical trial, inflammatory and noninflammatory lesions were reduced with IPL compared to no treatment.37 Another study reported clearance rates as high as 72% after 6 months.38 Overall, IPL may be superior to blue and red light, although it may be less effective than PDL.30
PDL, IPL, and LEDs have been compared in the treatment of patients with moderate to severe acne. The results favor IPL, which achieved a 90% inflammatory lesion clearance at a faster rate.39
